Maybe it's just me, but I think you're attaching too much negativity to a comment where there doesn't need to be any at all. We did stumble over the line in the sense that it took us 2 injury time goals to beat QPR, when at the start of that game I doubt there would have been anyone who would have envisaged us needing such a scenario in order to win the league, and for our last title win, we snatched it from Liverpool who (yes, as you rightfully pointed out, weren't able to keep their nerve and because of that pretty much handed it to us on a plate).
For both our title wins, I will maintain that we were worthy winners, we did deserve the title over the course of the season, but we didn't win the title in a convincing fashion (in the sense of winning it with points to spare or with games to spare.
