Except that Alpha Floor, relates to AoA not to speed.
From A320 FCOM 1.27.20
αfloor is activated through the A/THR system, when :
– α is greater than α floor (9.5◦ in configuration 0; 15◦ in configuration 1, 2; 14◦ in configuration 3 ; 13◦ in configuration FULL), or
– Sidestick deflection is greater than 14◦ nose up, with either the pitch attitude or the angle-of-attack protection active.
The αfloor function is available from lift-off to 100 feet RA before landing.
Following a GPWS "Pull up" for example. αfloor will activate almost immediately. It doesn't wait until the speed has reached a particular value. To associate αfloor with a particularly low speed would be a mistake.
