In a managed descent, the FMA is the power request of the FMGC to the FADEC, (i.e. - above profile THR IDLE displayed FMA.) The EWD is the actual power command by the FADEC - (right?) So even though we see the FMA change from SPEED to THR IDLE, we may not see a corresponding change on the EWD to IDLE because the FADEC may be commanding a repressurization/modulated idle segment at that time and thus a higher than expected N1.
