"Disney Princess" is a product line or something. It's not just a princess character owned by disney.
Mulan is a part of that product line (or whatever it is) even though she is not a princess.
Princess Leia and Star Butterfly on the other hand are both princesses owned by Disney, but aren't in the product line. I don't see why Azula would become part of the product line if disney got ownership of her.
