Effectively it does mean that the 2 are the most valuable of the SHs according to Robin
Narratively it will probably mean that it will be some action or things Zoro and Sanji will do in the final arc that will cause Luffy to become PK I imagine, oda is never really subtle with those type of things and he means them often quite literally.
Obviously all SH are relevant for that but i mean like a direct action in the fight around one piece that is teased
