I don't get the idea of this drill.

The exaggerated bent/arched left wrist through impact, all the pressure points behind the shaft, and the right arm decidedly below the left arm all combine to promote an open clubface and a dead block.

What am I trying to learn with this drill?

The resaon the right arm is below the left is because you go DOWN plane. The right arm and right shoulder drive the club DOWN plane into the ground. The reason his left wrist is arched is because he is hitting an impact back with lots of resistance. If it were a ball, the left wrist wouldn't arch like that. The dowel would move with the left arm through a ball, but in the demonstration the dowel doesn't move with the arm because it is stuck on an impact bag...the causes a bowing appearence of the left wrist. The pressure points directly behind the shaft will not cause an open clubface...if anything, they will promote a square one. Having the hands ahead of the clubhead has nothing to do with an open, shut, or square face. Left wrist control has to do with the clubface. The hands ahead of the clubhead is the key to good impact alignments.
