I'm not sure that I have communicated this very well . . .

I'm just basically saying that the right shoulder stays ON TOP of the left arm keeping the left arm down and the hand down . . . if the right shoulder motion is more vertical and UNDER it complies with a steeper plane and or a plane shift . . .

You see this a lot from players who have their body hiding the handle DTL past impact

I think I understand what you're saying. The Right Shoulder and Left Arm are aligned, but not to the Swing plane or the swing plane as we typically think of it. And the Shoulder staying on top of the Left Arm is an Alignment that will keep the Left Arm going Down.
