It can also mean something like "so he/she believes that...".
Here's an example:
Ion a trecut examenul auto. Figurile ca este sofer bun. => Ion a trecut examenul auto, si el crede acum ca este un sofer bun.
It is usually said in a condescending way, almost laughing at the person (but in a mild way, not a mean way).
I hope that helps.
