Forward handing to a lineman

[Warrenkicker]

I didn't get any replies to where I had posted this so I thought I would try again.

A has the left guard turn around after the snap so that he is facing his own goalline and is now 1 yard or slightly more behind the LOS. The QB hands the guard the ball in a forward hand-off. Then the majority of the offense runs toward the right while the guard runs toward the left and ends up scoring. Did this meet all of the requirements for forward handing to a lineman who is not an end?

7-3-2
No player may hand the ball forward except during a scrimmage down before a change of possession, provided both players are in or behind the neutral zone and it is to:
a. A lineman who has clearly faced his goal line by moving both feet in a half-turn and is at least 1 yard behind his line when he receives the ball.
b. To a back or a teammate who, at the snap, was on an end of his line and was not the snapper nor adjacent to the snapper.

So in 7-3-2b the rule makes a reference to "end of his line." It also uses the term "behind his line" in 7-3-2a. Is it referencing the same thing in these two rules? Some may say that "his line" is the offensive side of the neutral zone, which is how I have interpreted it. However with the wording of 7-3-2b, "end of his line," I think they might be stating that "his line" is the group of linemen, of which he is one, in their presnap formation. Since the end of the line-of-scrimmage or neutral zone is at the sideline it is not logical that this player, standing at the sideline, is the only player allowed to be handed to since he is already an end and doesn't have the turn-around restriction. So if these two rules are in fact referencing the same "line" then the guard would have to turn around and also take one big step backward to meet these requirements to legally accept a forward handoff.
