It goes on to say if it significantly exceeds Vmo or Mmo i.e. it's happened - pull speed and select lower, consider AP disconnect and use speedbrakes with care considering the pitch up moment whilst close to the ceiling.
In typical Franglais, I strongly suspect this is meant to inform you that the AP WILL ALREADY HAVE disconnected automatically, and you will already be experiencing a 'pitch up moment while close to the ceiling'?
So it's up to you to push the stick forward!
