I'm willing to grant that yes, it's a million to one odds that he didn't bleed out and nothing vital was hit, from 7 close range shots, if by "back" some of those rounds hit his butt and went through the deltoid or some such, but you don't see any exit wounds when he's got his shirt off.
More likely is that if he was hit a couple times, maybe some of those hits the rounds had already passed through someone else so there was very little energy left in the bullet. But he even says he was shot in the back while on the ground, which means that those were direct hits.
