Correct. Even better with the usual control column, the Captain standing behind could have also contemplated what kind of inputs were applied ...
No need for mechanicall movement to keep PNF aware of the control inputs, a vector display would work well. Lenght and direction of vector (line from a central "0" dot) would show the inputs.

But again there is no evidence that sidestick philosophy or mode confusion played any part in AF447, despite the number of people wishing it was so (I note CONF again forgetting that the PF was well aware of the occupant of the LHS taking control, which is one of the few things we do know about the flight deck atmosphere), so all we're doing is rehashing old arguments that are essentially a matter of personal preference and have no relevance to the subject at hand.
This is not about "awarenes" of who has control, it is about the PNF being able to follow what is going on, without knowledge of the control inputs in the several minutes before taking control he may not have been aware of the (almost) constant NU input.
