Thank you.
If you don't mind me guessing again I think it has to do with the dramatic increase of Vls with full extension. If you are already on manual flying and a protection kicks in on a undesired way the AP wouldn't be following the FD and you would override them.
Well, except if you are a Children of the Magenta (green in Airbus)
