I believe what you are referring to involved left and right sided 1/2 ball pivots, not one sided for every shot. Lol. Moore, at least in this match, is not pivoting. He is simply cueing low left prior to striking the cb everytime, like a golfer that's created a little waggle or club head grounding in the PSR just before swinging at the ball.
But you are correct in saying it's not worth discussing, especially if you insist on trying to convince anyone that Jimmy Moore is using half ball pivot aiming via the left side of the cb on every single shot...right cuts, left cuts, straight ins, etc.... There is no pivot system that operates like that. It's called rote, just seeing the shot and feeling/knowing where to strike the cb in order to make it happen. Many players cue very low center on the cb before stroking the shot, and it doesn't mean they're using some mysterious vertical pivot aiming method.
