Tactile feedback will come into it, yes - but it's worth remembering that the same thing happened to the Birgenair 757 which had interconnected yokes, and the psychological impact and tragic result was much the same.
Was there a UAS procedure training in force at that time? (I honestly can't remember) As I said before, my experience with Boeing ended long time ago in the early 90's and I can't remember training UAS at that time.
