That's a terrific demonstration of Hogan's late backswing left-lateral hip shift movement. It gives one the impression that the greatest advantage of the "move" is that it starts to replant weight onto the left foot and thereby brace the left leg, so that it can support the downswing pivot thrust action that is going to happen a fraction-of-a-second later when the downswing starts in earnest. I think that Hogans' "timing" and fluidity of movement is his greatest swing characteristic.

Regarding Shawn Clement.

He must transfer weight to the right foot at the start of the backswing if he is moving his arms across his body to the right. However, any weight shift is incidental and not a deliberate action. His general intention is to have a centralised swing that is rotary in nature. That's how I think of Hogan's swing - it's a right-centralised rotary swing with no deliberate intent to shift weight in a lateral direction. A key element in a rightwards-centralised swing is that there is rightwards spinal/torso tilt during the downswing, and one couldn't swing effectively with leftwards spinal tilt or with a head/spine axis that shifts left-laterally during the downswing. I like Shawn Clement's concept about bracing the left side with a rightwards spinal tilt. Here is link to another Shawn Clement video lesson that emphasises this point of bracing the left side via the biomechanical technique of rightwards spinal tilt.

Note that when he "braces his tilt" he juts his left pelvis in a left-lateral direction. Hogan did that same maneuver, but he did it in the his late downswing when he shifts his pelvis left-laterally.

In his one-leg swing video, Shawn Clement stresses the importance of having the right toe flared outwards so that the right hip can turn easily backwards during the backstroke. That allows the arms to move inside along an inside track, and get "deep" without any need for any deliberate independent arm-movements (independent of the overall directional movement of the shoulder sockets).

I personally think that, as a side-issue, that his lack of coiling (due to a free right hip clearing action in the backswing) demonstrates that coiling the upper body against the resistance of a limited lower body turn is not a necessary/obligatory requirement for very effective swing power.
