I don't think it makes sense. Like he said in his interview, he could have just sold the stuff he already leaked. Why then would he bother with the whole trouble of very publicly becoming America's Most Wanted? He sounded pretty sincere about doing this for the good of the American people. He claims he made a concerted effort to not reveal any information that could harm individuals, which appears to hold up.

I would think (hope) he has some cards up his sleeve to protect himself, but at this point I think all the double-agent/working with China talk is wild conjecture.
