If that is the ONLY shot he had...............then he had no shot......and before everyone says that "he killed it right?"......that doesn't matter. I shot a doe in the arse one time with a shotgun and I let her go for awhile and then tracked her in the snow and finished the job. She's dead too........doesn't make my shot any better or advisable to take in the future.......and I didn't even take a bad shot........she was quartering away and I either flinched or had a flyer slug. Hitting somewhere you weren't aiming for and getting a lucky kill is one thing. Aiming for a very low % shot and hoping is another. IMO.

I have shot deer in the neck with a gun and seen my brother drop a deer with a spine shot right in it's tracks with a bow. I wouldn't advise either shot ever be taken on purpose.
