[O.B.Left]

Yes, the bent right arm at impact means there is something left in terms of thrust through the impact interval. Compression resulting. Like a boxers punch the arm is bent at impact and then straightens.

Assuming one accumulator Basic Motion. The Swingers Right Shoulder takes the bent and passive right elbow downplane. The Hitter on the other hand, who actively straightens his right arm, zeroes out his pivot (to prevent having two accumulators powering) and therefor needs to pre position his Right Shoulder in a suitable position that allows for the right arm to straighten accordingly.

A good way to find this right shoulder position is to go to your desired both arms straight , Follow Through, Finish (Station 3) position and freeze your right shoulder there before going back to Address (Station 1). (Station 2 being Top in the Address , Top, Finish, Three Station triad.)

So your left hip notion might be good for some Finish positions but not all.

Hope this adds a little more precision to your discovery.

PS If you havent already purchased it the three disc Alignment Golf DVD discusses this and much much more in great detail.
