In the generally accepted actions, the players RARELY have their backs to the opponent involved in the play....they are usually facing them.

I think this is the reason that this does not draw more attention in the wording of the rules. But I still don't see anything which says that a player without LGP who leaves his feet could not then still draw a charge if the offensive player initiates the contact.
