IMHO CS are trying to show the effects of having zero hydraulics and the yoke has followed the control surfaces to their rest point after power down - cold.

I don't know if this happens in real life, would have thought the yoke was similar to the power steering system in our cars where there is some sort of direct connection but mainly it controls hydraulic shuttle valves. Very much unlike the Airbus FBW system.

Lou could very well answer this question.
