Jammedstab, after further consideration, I think I answered a question you didn't ask....
Pre-FADEC, if there was an uncommanded T/R deployment, the mechanical linkage that restricted thrust to idle would have had the affect of holding the throttle at the idle stop. Basically, since it was a mechanical system, that's how it had to work. We called it the "throttle snatcher" since it would physically grab the throttle cables and move them to idle - including the thrust lever.
With FADEC, that's all done with electrons - so there is no need for the throttle snatcher. If there is an uncommanded T/R deployment, there would be nothing that prevent 'normal' throttle movement in forward. It just wouldn't do anything since the FADEC would be commanding idle.
