you agree or disagree that the THRUST, as you put it, continues to both arms
straight to a point well ahead of the ball, and UNDER THE GROUND?
The Thrust of the Stroke always continues Down Plane during the
Follow-Through (1-L #15).
However, the Low Point of the Stroke is established at Impact Fix. It
may or may not be "under the ground." For example, in a Teed Drive, the Low
Point will likely be above the ground, i.e., in the air.
For a Putt with a Ball located opposite the Left Shoulder, the Low Point will
be on the ground. Only when the Ball is located on the ground
(or on a low Tee) behind Low Point -- in other words, a Ball located Up
Plane from Low Point -- will the Low Point be under the ground.
