I'm not being entirely serious (hard to be, given the little we know) but I'm not being sarcastic, either. Some of Snowden's behaviour has been pretty odd. A variety of interpretations are possible. One is that he's a mastermind media manipulator/intelligence operator/exploiter of immigration laws/meticulous planner of a fugitive. This idea has some traction on HN and outside but I'm pretty skeptical of it. The interpretation that I lean towards, mostly for Occam's razor-ish reasons, is that he's maybe a little bit naive and perhaps doesn't quite know what he's doing.
If you care about things like your credibility and being taken seriously you probably don't do things like fib about your salary or suggest the CIA is going to hire triads to have you whacked.
If you hope to avoid the reach of the US criminal justice system or intelligence services you probably don't meet, in person, with high-profile US journalists in a Hong Kong hotel carrying a Rubik's cube. You probably don't go to Hong Kong in the first place where your ability to predict your future fate is very limited.
And finally, if you hope to represent your prosecution as political and your acts as acts of conscience in defense of civil liberties, you probably don't start divulging operational details of overseas US intelligence operations to foreign governments - they're not related to your stated cause and just land you in much deeper doodoo.
Now, it's possible all of this is some diabolically clever ploy/gambit but, personally, I find that a little hard to swallow.
