You could genuinely believe it, and be willing to make predictions or even bets based on your belief, but that doesn't mean you've internalized it.
I agree that there's a distinction here, though it strikes me as one of degree rather than kind.
I would say the same thing about the two dragon-claiming, garage-owning neighbors... in both cases, their minds fail to associate representations of the dragon in their garage with various other representations that would constrain their behavior in various ways. Whether we call that "belief in belief" or "failure to internalize" or "not thinking it through" or "being confused" or "not noticing the implications"...
