It is to simulate the usual handling of non fly by wire aircraft.
i.e. during the flare as power is reduced the nose will want to drop, therefore requiring a steady increase in back pressure to maintain attitude.
I think if they would have not included the flare mode, the airbus would be one of the easier aircraft to land.
Get to flare height, pitch aircraft to landing attitude, reduce power and let the aircraft settle on to the ground. You could land it hands off.
Probably.
