My coach is pretty good about it. He does it when he sees people in positions that he knows he hasn't personally taught them or that they don't know that well. He tells them the escapes or what to do and although the other guy hears it and is now trying to prevent those exact moves it's good cause it basically turns into you trying to trill the technique of a move you don't.
If you kind of know the technique he'll say small subtle reminders.
