In the primer on the angle of approach etc. Yoda wrote-: "The Angle of Approach. This is the straight line drawn through the Impact Point and Low Point. It is likewise a Visual Equivalent of the true Geometric Plane Line and is best restricted to Hitting. Because the Inclined Plane is inclined, this Delivery Line goes out to "right field." The player Covers this Line with the Clubhead and Traces it with the Right Forearm and #3 Pressure Point to Deliver the Clubhead into Impact. Hitters may use -- but are not required to use -- this Line to guide their Cross-Line Thrust through Impact."

I highlighted the last line in bold. Why do hitters have the option of using and not using the line of approach to guide their cross-line thrust? What other options are there?

Secondly, here is this demonstration of the angle of approach on the ground - demonstrated by shining the laser light through the attack angle line which is drawn on the inclined plane. However, that laser light tracing on the ground cannot be the same angle of approach line seen by a golfer who views the angle of attack line from an eye position above the inclined plane. Shouldn't the laser light be shone from above - from the golfer's eye position?
