I think there is a time before the rally where that road is forbidden and considering Portugal will be in late may (I guess) I think Dani can drive wherever he wants in Portugal.
If I remember well Ogier went to Fafe rally sprint 6-7 month before they moved rally portugal back to Fafe area and had Fafe as Power Stage.

EDIT: I only read now Anttil quotes of the rules. The announcement of the itinerary is the moment after which you can't go in those roads. So it will explain eventually the Ogier's case.
