How on earth could looking at two naked men having sex make you a lesbian?

My assumption is that he's making a goof about the reason she likes the idea of man on man.  If she liked man on man because that means more women left out there for her than yeah that'd be lesbianic.  However if that were the reason you liked the general concept of man on man you wouldn't watch it, there'd be no reason to, you'd just like the idea that it's out there somewhere helping you score more ladies yourself.  

You like to over analyse everything don't you?

I couldn't help myself but try to think of what logic the brother could possibly be using, this is the best I came up with.
