Jack -

I think the shoulders/scap are loaded by tilting the front shoulder down and in early as you describe with the rear shoulder loading back and up as the hands cock.

The scaps then stay tilted this way as the arm action produces PLT synched with the front leg turning open/rotate bathead /rotate heel.

This coils the body as hands stay back and front leg then hips turn open.

There is then a superimposed "GO" move where the shoulders laterally tilt as the forearms twist to create THT at launch.
In the Wright clip you call this uncocking the shoulders.

I call this lateral tilt of the shoulders.

This is NOT turning of the shoulders.

This shoulder tilt action is slaved to the hands as the site of proprioceptive control.

The sequence is always handle torque starting first by arm action synched to leg action (rotate bathead/rotate heel/PLT, THEN

shoulder TILT (NOT turn) to produce THT at launch along with froearm twist which goe on longer for back forearm.

The hands alos proprioceptively control the direction and timing of weight shift along with the synched arm/leg action that started during PLT.

This means that at GO, when the shoulder tilt, at the same time,the hips turn/fire, but have to so within the constraints of the leg and weight shift action that is primarily supporting hands/forearms torquing handle and shoulders tilting to resist opening with the hips.

This controls the timing of the final twist/load of the torso between the hips and scaps and sets the swing plane direction to match the pitch location for square contact/generous contact zone.

If the shoulders scaps are TURNED rather than tilted, this rushes/dampens/slows torso coil and prevemnts quick unloading/acceleration with uncoicling.

The shoulder TILT (NOT TURN) is necessary to both keep the hands back AND accelerate the bathead quickly with a running start (PLT) boosted by shoulder tilt (THT at Launch).

The scaps thus resist, then clamp down on the torso to be passivley rotated by the quick well timed and well directed untwisting of the coiled torso.

The torso rotates/coils/uncoils.

The shoulders work to accelerate handle torque, produce resisting force so there can be early batspeed and good adjustment via feel in hands and connect to the well loaded torso.

IF you try to turn rather than tilt/"uncock" the scaps, you lack the necessary resistnace to turning with the hips and "rush" the loading/coiling of the torso and hands do not stay back, front shoulder does not (relatively speaking) "stay in there" and early batspeed is lost.
