It is not trained because it doesn't work. You can forcibly move the wheel to position of your choice but the FBW will return it to the position it deems to be necessary once you loose your grip and all the while will try to combat the trim with elevator to satisfy G demand.
There's no use and no need for manual trim while auto-trim is working.
A very important point, and i´m glad you mentioned it. I raised that question (how would the FCPC´s behave during manual trim when not in direct law) some moons ago. Nobody followed my lead there.
