Why would u cover The plane line?

That was just an example, golfers using the Angle of Approach do cover a straight line be it the plane line or the Angle which for ball back of low point is 10-5-E out to the right .

But it should be noted that a ball positioned at low point would have an Angle of Approach on top , square to the true plane line meaning that he or she would cover the plane line. Impact and Low point plane lines being one and the same.

In this instance the hitters cross line active right arm thrust however would still be geometrically correct given the thrust continues down and out to both arms straight not low point. See 1-L something or other. Its a revelation that one.
