In reply to KidParkinson:
It's an interesting question. Usually a well equipped route ends either at the top of the crag or a good and logical stopping place (like a big jug, a hands off rest or easy ground). This makes the clipping of the belay irrelevant. I'm surprised this doesn't go to the top because it's so close. I'd hazard a guess that those final moves are so easy they're trivial to do. I'd also guess that the long quickdraws are there to prevent the rope chaffing on the rock when lowering off. They allow the 'biners to dangle just below, rather than above, that little roof. But I don't know for sure, I'm just guessing here.
Megos certainly seems pretty ethical when it comes to his ascents, the first person I've heard of distinguishing between a first try ascent and a flash, so I'd doubt there's anything flawed with his tactics here.
