I'm guessing that he won't lose Shichibukai for some time. Even though he has aligned himself if they find out he is trying to take out a Yonko, it would work out well for WG. A lot of the information may have come to light from Doflamingo, after all he knew they were together and being an underworld person may have known of the other meeting. He may be attempting to just get the situation attention to by chance mess up Law's plans.
