The Greybeards have to have spoken with Paarthurnax as they view him as thier leader despite Arngeir being it de facto. By defeating Alduin you took his position as King of the Dov, but some othr dov may attempt to defeat you in an attempt to take the position as they might view the Dragonborn as weak for being a mortal. They might also simply be agast at the idea of being subordinate to a mortal and still desire to follow Aduin's "lordship".
