Angled versus horizontal hinge action.
Hogan's probably punching it with the right arm. Default angle hinge.
Or in his mind "holding it off". Hands too low will do that also.
Graham's swinging, default horizontal hinge caused by CF.
The face won't swivel onto plane until the clubhead overtakes the hands, with a left forearm swivel into finish.
Hogan held it off. He never did swivel onto plane in finish (in this photo sequence), typical of a hitting stroke.

Hogan and Yoda look great. Heads centered, good knee and hip actions. Neither are rolling to the outside of the left foot. Yoda's squatted more but those two photos seem to be from different swings, as he's on the practice grounds and the background has changed. Not even sure about the same camera location. We know he pushes that left knee out there but seemingly not too far, accepting the weight of the required parallel slide motion. (Tomasello did the parallel slide too, b-t-w, barely perceptible at speed but evident in slow-motion, and more than it looks. Several inches. He preferred to focus on the right arm and right shoulder and let the hips react, but keep 'em out of the way.)
I'd take Yoda's hitting stroke any day now if someone would just come along and transplant it.

Graham's hips haven't moved too far but his knees have, the head's dropping down and back, nowhere near the center of the stance, too much axis tilt, hips too open at impact, hands haven't caught up, shoulders could have traveled farther and release could have been delayed more. His "line of sight to the ball" got altered significantly. And it looks like he "stood up", almost like a S&T move.
Looks a lot like Mike Austin's "Flammer" photo sequence. Said he thinks "Try to lift the right heel." Hmmph. Not advisable.
