On the contrary, we think PF did NOT know where his SS was, relative to its own index, hence: "inadvertent aft input".
With a proper display of his own input, scratch "inadvertent".

Show the PF SS on the PNF display, so PF will not be distracted by information he already knows.
The information only shown if SS is moved from neutral so the pop up will trigger the monitoring pilot.
