I think it could be better if just checking the isRemembered on the subject, so client code could combine the isAuthenticated() and isRemembered() checks at will. The method could then be renamed to the straightforward isRemembered().

Or maybe I'm missing some point, @Sherpard ?

That gives flexibility but also some incoherence, you can be Authenticated, but not Remembered.

But you have a point on that, I'll make the modification ASAP and update the PR :)
