I think that what Mindy was trying to get at is that from an engineering perspective you don't want to "leak" energy by "disconnecting" the body too early in the downswing. The release is then "automatic" in that the angles are released by the motion and not consciously by the player. I think this is, as you say, what Mindy actually does. On the clubhead speed issue I remember once as a much younger person having a computer fitting where the pro measured my driver speed at 117 m.p.h. but advised me to try to slow it to 100m.p.h. to improve the impact and get more average distance rather than the odd long drive. Maybe this is what Mindy was feeling in his game? A slower swing with better impact conditions yielding longer shots.
