No, "ask" shouldn't have this problem. Each ask() operation creates a little pseudo-Actor under the hood, which is unique for this operation, which will be the receiver of the response. So long as the Actor is responding to sender(), the response should go to the ask() that initiated this message; cross-talk shouldn't be possible. (This is actually a very common situation.)
