When you look at 1-L and the hinge, notice that the secondary hinge in the dual horizontal hinge action, that lifts the left arm up and down which actually is what the magic of the right forearm is all about - any bending of the right arm with extensor action will lift the left arm in a circular motion around its pin. In the dual horizontal hinge the left arm is lifted till the top of the backstroke, goes back down till low point and then lifts again till the finish of the stroke. The constant 'onplane' pressure of pp3 towards the plane line as pp4 drives the lever assembly is what drops the left arm onto the ball...
Because the stretch is also onplane as pp4 pressure is created against the lever assembly, and the fact pp3 is also on the plane and your pp3 won't be offplane (I hope), as the pressure of pp4 works against the onplane pressure of pp3, this tilts the spine and drops the right shoulder axis tilt until pp3 can trace down the plane line.
Also the pressure of pp3 towards the plane line is what keeps the level condition of the right wrist....
