There's no reason to assume that this guy was ever IN Nepal. According to the caption, the photo was taken in Darjeeling -- Darjeeling is a hill town in the northeast of India. It's part of a circuit frequented by expats and tourists that might (thinking of the rail itineraries here) reasonably include Varanasi, Bodh Gaya, Calcutta...
I agree that he doesn't strike me as American -- more European in look. I say that largely because he's slim and his clothing accentuates his slimness (ie is form-fitting) in a way that most North American guys' clothing is not. Moreover, his clothing looks like he bought it at a local bazaar -- it looks like the product of a local tailor -- which marks him as either a low-budget expat or a low-budget long-term traveler, IMO.
