A320 Flight control law Landing Mode

[Reverb_SR71]

Hey guys

Fcom extract " At 50ft the attitude is memorized as reference pitch attitude .

At 30 ft this value is progressively reduced to 2degrees nose down to induce a gentle positive action for a conventional flare "

Please help me understand the logic behind this.

How is this supposed to help the pilot make a conventional flare ? do non fly by wire aircraft pitch down on their own in final descent ?

wont the pitching down increase the rate of descent close to the ground ?

also when in direct law i am assuming this wont happen so is there a marked difference in landing the 320 in direct law when compared to normal law ??

Thanks
