As an aside, I once landed an A320 or 321 which had a reverser locked out. Our SOP in this situation was to put both thrust levers into reverse rather than just the one that was working.
However, something went wrong and when I applied full reverse to both engines, the good one went into full reverse but the faulty one went into FORWARD thrust at whatever N1 full reverse is. As a result the aircraft suddenly pitched up, lifting the nosewheel off the ground and yawed. This was completely unexpected, but I instinctively controlled the aircraft with rudder and elevator, and cancelled reverse thrust and brought it to a safe stop.
