Maybe it's his experience, but he gained his knowledge on Unix and Windows, and does know his onions. He searches out rootkits manually, without needing the security software that you and I always use. He maintains large systems for large companies, and has even worked abroad because he was headhunted for a particular job. He's not a numptie like I am. Just because he hasn't had the same experiences as you, or me, doesn't mean that he can't state his own eh?
