Right Shoulder Down Plane...

For swingers (manipulated hand swingers), what makes or allows the right shoulder to go down......plane????????
I would say secondary axis tilt. As the hips slide forward, the right shoulder drops. In my own swing it's a double edged sword: I can use hip slide to send right shoulder down plane or focus on right shoulder going down to create axis tilt. Am I perverted or what?
I am bascially with broberts5. With hip slide, stationary head and rotation the right shoulder has nowhere to go but down plane.
