Hi Pensador,
I agree with CP - there is a clue in the FCTM page A027 P1/2.
"In the QRH, the line, "SPEED SEL............VFE NEXT -5 kt" is designed to allow the crew to configure the aircraft for landing whilst controlling the speed in a safe manner. This procedure may involve reducing speed below the manoeuvring speed for the current configuration which is acceptable provided the speed is kept above VLS. The speed reduction and configuration changes should preferably be carried out wings level."
