Non- pivot foot

For the wind-up position, the *entire* pivot foot need not be on or in front of the rubber. For the set position it must be (that's the second clause of the sentence you quote). See 6.1.1A

I understand what you're saying, but the only case play that addresses it is 6.1.1 SITUATION A. All other case plays use the phrase, "F1 steps on the pitcher's plate". What I was getting at was, the only time the pitcher may legally contact the front of the rubber is from the set. The few times I've seen a pitcher start a windup with his heel up against the plate, they lose contact with the rubber during their deliveries way before they should.
