One is from the post-missile strike TV appearance (uniformed with glassses). The other is from his recent Dan Rather interview.
Personally I think it's the same guy in two different outfits. I don't imagine he had his beauty sleep...
They're not saying, and how long does it take to analyse a few photo frames? One theory is that if they didn't kill him with the missile strikes, the next-best result is to force him to make TV appearances so the signal intelligence units can try to pinpoint where they are coming from.
That being the case, he might still be alive but sending his best double to do the TV spot.
