The relevant part to this question states that once the approach mode is activated on the FMGS (or a number of other relevant criteria), then the speed target is:
The limiting speeds are not target speeds, they are exactly that, limits. The aircraft will only reduce down to that limit until the limit is removed and it can reach it's target speed. Similarly, the aircraft will pitch to not exceed Vfe, when accelerating to enroute climb speed, if flaps are still extended.
