I frankly don't think it's a big deal. Sure, I'm absolutely certain the guy doesn't have OCD, and that he's probably rather "anal retentive" in some fashion.
Of course, who calls themselves "anal retentive" publicly, as it is almost exclusively negative in connotation. So, he uses the term OCD, sort of how people use "retarded" in a sentence like "lol, I guess I'm a bit retarded when it comes to XYZ".
