Is it weird that my boyfriend hides his relationship status on facebook?

I've been dating this guy for two years and he just recently joined facebook. As soon as he joined I updated my relationship status to include him and he updated his relationship status as well to include me. Both our profiles can be seen by our friends and college network. I discovered that people in our college network can't see that he's in a relationship. Should I be concerned?
