RichMSN wroteNo. Prior to a change in team possession here simply means that if possession changes (and changes back), then it's a running play. A change of possession isn't a necessary condition for 2-33-1c (or the other citation from rule 10) to be in effect. A fumble behind the neutral zone is a loose ball play and A benefits from fumbling the ball here.
Well that's what I thought. In that case 2-33-1c is grammatically incorrect. Shocker, I know. 🙄
