Why does a guy talk about another girl?

elle20
Let's just say the scenario is this: a guy is attracted to a girl talk to each other daily and see each other at least 3 times a week. Then, suddenly the guy talks about another girl say how cute she is and how she looks like the girl's little sister. Why would a guy say that to someone they are attracted to? Is this guy somehow fishing if the girl will get jealous?
