From your source:
“While the original goal of the Human Genome Project was to order and orientate every base pair, that couldn’t be achieved because the technology wasn’t sufficiently advanced enough. So we finished the parts that we could finish.”
This strongly implies that even with twenty years additional research they did not complete 100% sequencing otherwise it would have stated that they had actually done so instead of "So we finished the parts that we could finish.”
Additionally from your source:
There’s still room for improvement. The new sequence comes from essentially half a human—that is, half of the genetic content normally found in a person’s DNA. Each person has two sets of chromosomes, a maternal and a paternal one.
