If you are talking a diesel you are correct. On gasoline engines both
air and fuel must be regulated TOGETHER. Either fuel is shut OFF or
the throttle (air control) needs to be closed in concert with the
reduced fuel flow.

They have to be regulated together *under normal conditions* in order to
maintain emission standards. That obviously isn't important in an emergency.
Reduce the fuel flow to a trickle, and the engine *will* slow down, regardless
of what happens to the airflow. Under runaway acceleration, the primary
consideration -- indeed, the only consideration -- is the need to get the car
stopped. Any damage that may or may not occur to the engine or the cat is of
comparatively little importance.
