Just to judge her reaction? See if she cares or is into you? And then say "it's only been a couple dates, it's not serious" when she asks about it or the other girl. Would you do that?

It really depends on where the two of us were, and how the conversation was going. Context is everything, and we don't really have any here.
Assuming you weren't going out, and assuming he's not even sure if you like him or not, he may have said it just so you know that other girls find him desirable. And a lot of the time, that actually works, because women tend to like men that OTHER women like (they feel like other women have already vetted him), and they often tend to like what they cannot have, or is a challenge.
Now, you can also very easily make yourself into a douche-bag braggart by saying this the wrong way, and you can come across as just being ultra-honest and up-front. It's all about the context.0
