Control inputs do not confuse the flight control computers. The Bus flies just like any other aeroplane. Adjust pitch and roll as required to achieve what you need. If you want to take over, say "taking over" and press and hold the button, just like you are taught to. It ain't rocket science. But you need to recognise what is happening, and know how to fix it. Doesn't matter if it's a bus or a Boeing, A bad pilot will bend it.
