I think a lot of confusion is that most relate everything to the ground.

If the swing is always moving "down" until the shaft is in line with the lead arm, the one can still be swinging "down" yet with the proper axis tilt, can be swinging level or even "up" in relation to the ground.

I would even venture to say with an iron swing, low point is not at the bottom of the divot, but at the point where the shaft lines up with the lead arm (low point could even be after the club has left the divot and is above ground.

I most certainly agree. Perhaps it is more useful to think of 'low point' as the point farthest away from 'center', rather than it having any relationship to the ground.

There is a difference in perspective between the low point of 'force' (both arms straight) and the low point of the clubhead (at left shoulder, relative to ground, right arm stil bent).

This, IMO is the core reason for 1-L-15.
