I agree to some extent but i still believe normal swing to be less complex. Its simply due to air flow etc like you said. You don't need to angle the seam neccessarily. I used to be a swing bowler before a string of shoulder injuries ended me. Reverse swing is a hard art to master because there are different theories on how it works. Some people don't only rough up one side of the ball but also try to make it heavier by loading it with liquid like sweat, saliva etc. some disagree with this saying it just makes one side of the ball soft which is counter productive. This is something I think comes down to where you play cricket. For instance in Australia the balls we use (predominantly Kookaburra) don't last as long and soften up a lot quicker. The balls used in England are a lot harder wearing because the pitches are rougher so balls need to be more durable. This assists reverse swing in my opinion because they stay hard but can be roughed up and weighed down on one side.
Also action has so much to do with it. Reverse swing isn't predominant in Australia and that is possibly due to the standard actions of aussie bowlers. English actions are much more condusive to swing.
With the taped up tennis ball, i would think that is more due to the uneven nature of the ball. Once one side is taped its a lot heavier. Also i don't think a tennis ball is a good comparrison because its so light so he behaves different to a heavier ball anyway.
