TGM teachers usually recommend (often recommend) the RIGHT SHOULDER AS BEING THE SHOULDER THAT INITIATES THINGS ON THE DOWNSWING, NOT THE LEFT. The Right Shoulder, of course, must move properly, and on plane.
The PHYSICS part of golf is interesting, and can get tricky, especially when there are some FEEL vs. REAL factors.
This is just a reminder for everyone. Jorgensen's book is based on a model of the golf swing that he created which specifically fit a PGA pro in the 70s when the research was done. It is not a model that would fit every swing or even the most efficient, powerful, or accurate swing (it might or might not). He also does not divulge the pro he used in his work.
That being said, the physics is sound within the assumptions provided. Since PGA touring pros tend to have pretty good swings (slight humor here) and do most things correctly, general conclusions can be drawn somewhat from Jorgenson's work, but there still might be some ambiguous or misleading conclusions as well. I have never read the other paper referenced in the link and so cannot provide any insight into it.

Hi Lagster, i always thought it was just the intention of driving the right shoulder down plane but it didn't actually move first (at least for a swinger anyway), but the movement was initiated in the feet and hips. Seems like to me that his talk of "pulling with the left shoulder" is actually very TGMish cause is sounds like he's just describing #pp4.
The "pull" is from the Pivot Train that starts at base of the lower left limb aka the foot, then the shin, the thigh, the pelvis, etc..."pulling" from the Pivot is the result of sequential and segmental motion ....there is an acceleration of the segments and braking of the segments thus causing a built up of torques and the creation of angular momentum....Thus the myth of hitting into a frim left side..the firm left side feeling is the summation of torques created by the segments of the left side "blocking" much like that of a pitcher or quarterback who strides and then performes a sequential motion of the joints and segments to throw...this is the swingers transfer of momentum...Certain things are in motion and other things are stabilizing....
The Hammer Thrower is a great example of Sequential Motion
The Shot Putter is a great example of Simultaneous Motion...
Field Hockey is the closest I've seen to golf...

Technically, you are correct that the first movements in the downswing are from the ground(feet). When talking about the role of the SHOULDERS, however, TGM rarely even mentions the left shoulder. Mr. Yoda has written many, many times about the role of the RIGHT SHOULDER, and how it's proper on plane motion accelerates the swinger's left arm.
Now, if a player likes to FEEL the left shoulder moving up and back instead of monitoring the RIGHT SHOULDER moving down towards the ball, and gets good results, it's OK.
Annikan's post here about sequencing etc., by the way, is very interesting.

You can get more players to get the right shoulder on plane by telling them to move their left shoulder up/back then telling them to get the right shoulder down plane.

Using that article one can certainly explain the why and how some golfers can hit from their knees or sitting on a chair just about as far as they hit when standing on thier two feet.
When Annika won the Women's US Open, in one of the post interviews she was talking about smoothing out her body to get her swing back on track.
