The section i am refering to is when he delivers/throws the butt end of the club into the ground where the ball would normally be positioned.

Arrowing the ball with the butt end of the club is something that Gregg came up with to teach the student Aiming Point per 6-E-2, Drag Loading per 10-19-C and a Straight Line Delivery Path per 10-23-A.

In regards to throwing the butt end of the shaft into the ball, If I understand you correctly, my guess would be that this obviously is in the context of creating solutions for those that have throwaway- or release the club too early. It may have some useful applications in correcting those problems. However, I would say that there probably is no where in a golf swing where you could let go of the club and the shaft would arrow into the ball on the ground...

I have not seen the Greg McHatton video and therefore cannot speak to the referenced drill.

However, my own Gallery 'live lesson' demo (where I throw the 'javelin' at the Ball) demonstrates how to establish the precise Down Plane Delivery Path of the Hands -- the Line of Thrust from the Top to the Aiming Point.

The Clubshaft and the Clubhead have their own Inclined Plane of Motion. Both are controlled by the selected Delivery Line. That is, the player Traces the Geometric Plane Line or Covers either of its Visual Equivalents, the Angle of Approach (Hitting) or the Arc of Approach (Swinging).
