Your description fits my previous understanding of hitting. However, after watching the LB hitting/swinging video in his video gallery, I am now led to understand that there is no pivot action (right shoulder downplane thrust) - neither gentle or assertive - in a hitters action.

Mmm...
in the video (at 00:55') Lynn says that for a Hitter, the right shoulder must not drop down (ie underplane) [EDITED, was "downplane"] but drive down the shoulder plane. It doesn't mean the shoulder must stay back or that there is no pivot action!
The shoulder is free to move if it moves down the shoulder plane!
Then the right arm thrusts against the right shoulder.
In fact, if you don't move your shoulder down plane (using the pivot I guess!), you will certainly run out of right arm and will be forced to throw away!
