If the Hands are a portion of the Lever Assembly and they do not move in a circle as your 'proof positive' demonstrates, haven't you negated 1-L-8 and 1-L-9?

1-L-8. No portion of the Lever Assembly can swing forward independently.
1-L-9. Regardless of how the Lever Assembly is driven, it moves in a circle.

How can the Hands move in a straight line but the Lever Assembly move in a circle simulatenously? The answer is the Axis Tilt during Start Down performed with a Stationary Head and Hip Slide towards your selected Delivery Line.

1-L-21 is referring to Machine relationships. We humans are not machines and have extra components that make the Golf Stroke more complicated. This is why you cannot demonstrate Axis Tilt or slide Hip Slide on the geometrical figure of 1-L.
