Black Pudding - FCOM states:
"All actions performed on the FCU and MCDU must be checked on the PFD and ND (eg.: “FL 350 blue”, “FL 200 magenta"). Ensure that the correct FCU knob is used, then verify indications on the PFD/ND"
So it is probably more like FMA Fiction, PFD Fact.
There are also specific FCU commands by PF listed in FCOM, mostly used when AP is OFF e.g. "MANAGE SPEED", "HEADING PULL" etc.
