I always figured that Carey meant to put a line in there saying that the first officer was a cross-dresser. Or else those two women we saw on the screen were not part of Bateson's bridge crew, but were the heads of other departments who were talking to Bateson when the events occurred, and thus ended up on screen with him when he was talking to Picard.
I always figured that she just didn't actually pay attention to Cause and Effect. We already know she didn't pay attention to Best of Both Worlds and Chain of Command, so it seems the simplest explanation.
