Okay, this is kind of correct, but there are some minor and major mistakes.
The main and only practically significant drug in suboxone AND subutex is Buprennorphine, correct, although the way it is really spelled is "Buprenorphine." And yes, I like to be a dick whenever I get the chance
Yes, bupe is a mixed opioid agonist-antagonist. The following will explain the real meaning and significance of bupe being a mixed agonist-antagonist opioid.
What this means is basically that, in the sense that bupe is a partial opioid agonist, it will have some of your standard, morphine-like opioid effects (causing analgesia and euphoria for instance). Most, if not all, opioids used to treat pain or chronic pain are full opioid agonists, such as oxycodone. But remember, bupe, unlike oxy, is only partially an opioid agonist...
Thus, as it is only a partial agonist bupe's agonist properties, such as euphoria and analgesia, are not as pronounced as they are with a full agonist, such as oxycodone (thus people can easily catch a nice nod with oxy but it's rather hard if not impossible to do so with bupe, although it certainly will still make you feel damn good).
[The best known full opioid antagonist is Naloxone, best known as Narcan, which I discuss briefly a couple paragraphs below.]
In the sense that bupe is a partial opioid antagonist, thanks to its extreme high affinity (think of bupe a REALLY strong magnet) to your opioid receptors, it prevents (the vast majority) of other full opioid agonists (think of something like hydrocodone, for example, as a much weaker magnet) and full opioid antagonists (Naloxone/Narcan) from attaching to your receptors in significant numbers.
Bupe has such a high affinity for your opioid receptors that it will even kick off and dislodge previously attached full agonist opioids from your receptors. This is the cause of precipitated w/d (happens when you take bupe before all other agonist opioids are out of your system), and why you must wait 12-48hrs (depending on the full agonist opioid in your system) before you can begin taking and titrating your dose of suboxone/subutex.
Thus while bupe is in your system, it's antagonist action, thanks largely to it's extraordinarily high affinity to your opioid receptors, prevents other opioids from having much if any effect on you. But remember it's still only a partial antagonist, because as I mentioned previously it also has morphine like agonist properties.
That is why we call bupe a mixed/partial agonist-antaognist opioid. BTW, opioid means any morphine-like drug (as in chemical structure and/or effects).
For your average lay person all that takes a bit of thought to wrap your head around, but it's not really all that complicated to understand once you've figured it out.
Here's the big problem with your post: Suboxone/Subutex IS PRESCRIBED for pain managment in certain populations (i.e. if you're an addict and also suffer from chronic pain).
Naloxone is the drug in Narcan, which alone, as a full opioid antagonist, is used to treat people who have overdosed on opioids. Naloxone is thought to deter abuse of suboxone (it's not in subutex), however it does little to nothing to actually do so. This is because the bupe in the suboxone renders it useless, out-competing the naloxone. The bupe in suboxone just doesn't give the naloxone any chance to attach to your opioid receptors.
(Narcan is also used to treat bupe overdoses, rare though they might be given it's ceiling effect, but you have to use much more Narcan than you normally would when treating someone who has overdosed on a full agonist; Narcan will probably have to be administered multiple times as well to treat a bupe overdose.)
(Notice how, with a big enough dose of Narcan you can treat a bupe overdose, just as how you can get high while taking bupe as long as you use a big enough dose of a full agonist?)
Thus, it doesn't really make a BIG difference whether you're on suboxone or subutex. Doctor's mistakenly believe that it's the naloxone in the suboxone that makes it "abuse proof," when this is absolutely not the case (as the naloxone doesn't really do anything, unless you're allergic to it I mean, and in that case you also will probably be allergic to the bupe itself). People can still shoot, snort, plug or take suboxone however they please. In terms of pain management, both suboxone and subutex work pretty much as well as one another.
Taking full agonist opioids (hydrocodone, oxycodone, morphine, hydromorphone, etc. etc.) while on suboxone or subutex is highly impractical. To do so effectively you'll need to take many times your normal dose to achieve any effect (because the bupe is out competing them, thus blocking and preventing them from attaching to your opioid receptors in significant numbers), and as Zneg notes such high doses can pose risks to the user themselves. (That being said, I have been able to get high from both heroin and oxycodone by taking much, much more than I normally would have while I also had bupe in my system.)
But given bupe's ability to treat many forms of chronic pain, other opioids are generally not needed for pain management when a patient is using bupe. Tramadol is often prescribed in conjunction with bupe, as it does not work like classic opioids and thus is not affected by the bupe. Of course if you need some sort of medication to treat break through pain that is stronger than what tramadol can handle, you can work out a viable option/dosage of suboxone/subutex to make another opioid possible (I believe there are other opioids with an affinity to your receptors that comes pretty close to if not surpassing bupe's affinity).
The best point in the above quote is that suboxone/subutex should only really be used by those who plan to stay the course, and use it long term. It is not the kind of drug that lends itself to just taking once in a while to treating chronic pain, although I do know one individual who's successful for the most part in so using it.
By the way, although most do not get "high" from it after the first day or two they're on it, many do feel a positive, analgesia and euphoria from suboxone/subutex EACH AND EVERY time they take it (such as myself). So until you try it out and get used to it, you can't really predict how well it will work for you. But honestly this goes for ANY and EVERY drug...
Again, I want to emphasize, bupe is a great tool at treating chronic pain
in certain populations (especially those who have chronic pain and are also former opioid addicts or habitual abusers of their pain meds). Of course it doesn't work as well for everyone, and its efficacy at managing chronic pain will depend largely on the type and severity of your symptoms. But this is for your and your doctor to work out.

Shit, when I get going about suboxone, I sure do get going...
