I posit that some of it is just people lying. I had someone send in a huge perl script he claimed to be his own work yet failed that variable swapping test. Basically our setup was HR gets a bunch of resumes and scans for minimum requirements (degree, prior experience) then we get them. You get really good looking resumes that you need to prove somehow. That's where that basic litmus test comes in. Things like Github improve this a bit although I'm not even a huge user of public github repos (something I'm working on fixing since I realize my online profile is a bit sparse at the moment). I don't it's perfect either as a lot of very good candidates don't have time or are shy to show they work in public. Heck I love working on my professional project in my spare time and can't show that code publicly most of the time.
