Agree. If I'm on clock duty, there's no way on Earth I'm signaling the attempt at the end of a quarter/game when it's not going to count anyway. The half second delay I take to debate released-in-time/didn't-release-in-time through my mind is going to cause waaaaaay less of a headache than if I signal a 3 and then wave it off like the official in the OP video.
