So, assuming we did not see every little thing that happened in the forest of death part of the chuunin exam, it's possible that Sasuke had opportunity to test out Lee's move, which goes a long way to explain why he could pull it off so effectively during the preliminaries.

that's not the problem.
it's just jarring, that we've seen Karin for about two years now (or something?) and we never even heard about something to suggest this connection between them.

it's like we get to see some 3rd rate ninja of Konoha dying, and then in his flashback he'll suddenly turn out to be Kakashi's best friend. or Naruto's other father figure.

expecting Karin to match to one of the contenders in the chunin exam is far above what I expect from Kishimonto (it's not like he's god, or Oda). but come on, this is the first time we hear about Karin's past, and suddenly there's a connection between them?
