Its darn obvious he is not talking about Sakura but Sai. i dont consider one time in the forest "often". Sai mentioned "him" when oro appeared. therte seems to be a back story with Oro and Sai. Perhaps Sai's brother was murdered or was a test experiment for Oro.
Sai said "so that's him..." it shows that he has never met him before.

edit: also, at the last page, Oro said "it seems the kyuubi boy is here as well...i've seen that face a number of times" meaning that he's refering to naruto
