It should be added to your sentence, "until the slats are extended"... but now, without valid airspeed, this is another question rising as there is also speed limitations to their extension.
Concerning the FCOM, this part is quite old, it could have been modified later. But you are certainly right that its litteral "meaning" is not exact (and curious in such a manual). They certainly meant something else like no rudder "active" protection is part of the flight envelope as for roll and pitch axis.
