To answer the OP: in flight the FBW continually changes pitch when the side-stick is held out of neutral - the rate of change is determined by how far and for how long the side-stick is held out of neutral, so the pitch is not directly related to the side-stick angle but to the time and distance the side-stick is held out of neutral. The FBW also holds the new attitude after the side-stick has been centred.
During the flare this would make fine control awkward - pilots would have to nudge-centre-nudge-centre etc., which would make fine adjustments difficult and delayed. The flare mode is not about pitching the aircraft down, but it uses that to force pilots to pull the side-stick out of neutral and to hold it out of neutral against the centring spring to maintain pitch. Now the pitch is effectively directly related to side-stick angle: pull harder = higher pitch, pull less hard = lower pitch. This is more conventional and more instinctive when small, rapid and accurate adjustments are required.
