Airbus overspeed

Recently when flying with a new captain on the bus there was a discussion about flap exceedance and Automatic Flap Retraction system. My take on the function was that the flaps retract automatically at 210 and then the aircraft accelerates to the managed speed 250kts during which time if we don't retract flaps then we get a Overspeed warning.

However the captain was quick to point out a line in the FCOM which reads

"If the managed speed/Mach target is set above VMAX (VFE , VMO , MMO ), the FMGS automatically limits the speed to VMAX"

Going by this line the aircraft should maintain 230 kts and we'd never get an OverSpeed warning. I sense something is amiss, who among us is correct?
