You don't play a 3 iron and wedge at the same location relative to low point.

Mmm, sorry Augusta but I don't get what you mean by "same location relative to low point"

Say you play your driver at low point with the ball on the ground. Result: zero divot.

Now, with exactly the same motion, place your low point under the ground (and not at ground level as with the driver example) and a wedge replaces the driver.
To be properly contacted, the ball must then be positionned up plane (that is back in you stance and closer to you).

You all know it: Because the motion is on an inclined plane, you will contact the ball first, then the ground down and out to low point.

Maybe I'm wrong but I'm pretty sure G.O.L.F is working like that!
