PC foul?

The official was signalling that the shooter was shooting a 2-point attempt - his right foot was still in contact with the floor when he was fouled and before he became airborne. He did this because this particular shooter was previously behind the arc and executed a move to draw a "foul" - the shooter even looked over his right shoulder to find the defender. The proof is that the official extended two fingers towards the ground where the right foot was located.

I don't use that phrase or signal either for the same reasons you mention above (not to mention it isn't an approved mechanic). I was just pointing out the fact that it looked like that was what the official was calling in the video, although looking at it again, I think your reading of what the official was communicating is more correct.
