I understand that purifying Sasuke of Orochimaru would, say, removed the cursed seal. Since the seal is a part of Orochimaru.

But causing him to just...forget all of Oro's techniques. That doesn't make a whole lot of sense. I mean, what does being able to Summon Snakes have to do with being controlled by Oro?
Well I don't know, he did sacrifice the king snake. That could have pissed off a lot of the other snakes thus voiding the contract, and he didn't really have too many oro-related techniques that didn't involve something snake-like. Not positive whether or not he used snakes since the sacrifice. If he hasn't, it would make more sense. If he has, well, regardless he still lost the abilities.
