I agree with you that Hogan's transition pelvic move is important, but I think that the value of the "transition move" relates to the creation of the optimal skeletal structural alignments necessary for an optimum downswing pivot action (see post reply to dkerby above) and that it has has nothing to do with moving passive central body mass closer to the left leg. When Hogan shifted his pelvis left-laterally in the late backswing, he optimised his reverse-K alignment before starting his downswing pivot action in earnest.

To reinforce my argument that body alignment places a major role in swing power, look at this swing video of Shawn Clement swinging off one-leg.

He can hit the ball as far, if not slightly further, off one-leg than two legs. Why? Note that he has no body coiling in his one leg swing, and therefore zero X-factor, and the absence of any coiling of his upper body against the resistance of his lower body doesn't affect his swing power. I think that a key element in his one-leg swing's swing power is the method that he adopts to position his spine with rightwards spinal tilt at address. That maneuver creates the braced reverse-K structural alignment necessary for his "efficient" downswing pivot action over one-leg.
