Trust your instincts. Your are conveying this to us because somewhere, that small voice is speaking to you. There is nothing wrong with remaining anonymous for any number of reasons. Like someone else said, this person may be dealing with some demons. He may worry about privacy...but presenting as one thing and admitting to being something else is a red flag. It isn't a show stopper, but I would proceed cautiously and not be offended if he isn't ready to reciprocate. There is a reason for this---and you don't know what it is yet...so use caution.
