Naji said the same thing the other day. I don't know where you guys are getting this from. The stroke is the pullback, and then the forward motion of the cue. What you are saying is the stroke is called the follow-through. As a point, you even call it a "warm-up stroke". Who does warm-ups on the follow-through if that is the only part that is the stroke? Just the fact that it is called a warm-up stroke should make you realize that it is the motion of the cue, not just the follow-through that is called the stroke.
Quite right, other wise Busty would have no stroke as he starts off a foot from the CB
