I'm not sure that I understand your sarcastic comment.
If you are down 9 points and kick the XP (95% probability), you are down 8 points. You can now tie the game if you get a TD and a 2-point conversion. You have basically extended the game, because there is a chance to get the ball back for one last scoring drive. But if you go for 2 points and miss (50% probability), you are still down 9 and now you need a TD and a FG to win. Given the limited time remaining to execute two scoring drives, you have effectively ended the game if you don't convert the 2 points.
Coaches are increasingly going for 2 points in these types of situations, and I just don't get it.
