For years, before Behance redesigned their layout (which I think was sometime last year), the way that it sorted projects when you stumbled across the site was by popularity, so the popular ones just kept getting more popular. A project called the "Facebook Facelift" from 2009 (http://www.behance.net/gallery/Facebook-Facelift/314489 http://www.behance.net/gallery/Facebook-Facelift/314489) was (is?) the most popular project on the site, and is equally thorough with a video to boot. I'm going to take a guess that the designer here was looking to piggyback on the success that project had, rather than create an honestly useable/consistent design (not that this is a justification of how poor some of the concepts are, but rather a reason why someone would spend so much time working on something as tedious as this despite the UX issues it creates).
