In this case, he even intentionally intentionally triggered the crash. As cool an achievement this is, I struggle to call it "beating" the game, since players could still theoretically go much further. Given that the glitch is predictable and well-documented, I'd consider it to be yet another (and new) obstacle to overcome, not the end. This is therefore the first time someone's ever hit the obstacle, and the first time someone's ever passed it (since he missed his first chance at glitching and had to take the second).
All that said, I feel a bit weird telling a community I don't belong to that they're incorrectly enjoying a game I don't play.
