Not really, no. The light on the hands could just as easily be a reflection of something. I have a couple photos taken with a fancy canon SLR which have become a running joke in our household because they look so fake, but aren't.
It's also worth noting that the difference in lighting can be explained by the bamboo. The guy in the blue is getting direct sunlight from the right of the frame, but McAfee is, in part, shielded from it because of the plant.
It probably isn't fake. The original image is also a better resolution where it looks much more real.
Where is that better resolution picture? All the ones I've seen look fake to me. And not because of lighting. The image of him just looks very flat. No depth. And the angles of his head to body look like a picture was taken of him at a slight angle, printed on a flat board and then placed straight to the camera.
