Sounds like convoluted thinking. In his first group he claims that they don't "believe" in a god or gods, though doesn't elaborate on exactly how that's significantly different from the other saying that in the absence of empirical evidence there's no reason to believe in god (b/c w/o evidence he can't really exist anyway), which is the same as saying I don't believe in god b/c no one can prove he exists. Both ultimately rest on the belief that if you can't show empirical evidence of something, it's simply imaginary.
