That makes no sense. Not cutting Sasuke in half doesn't mean anything when v1 Bee with only 3 tails can create this match destruction by crashing into the ground.

. Don't know where this 'overpowering Ay doesn't count' but it makes no sense. The only reason v1 didn't cut through Sasuke is because he'd be dead and that can't happen. But we've already seen what a v1 2 tailed Naruto could do (who's not too different from Bee) could do, and he sent Orochimaru 100 meters+ away with one punch and ripped his arm off. It was merely for plot that Sasuke did not get bisected, it doesn't detract from Bee's other feats.
