Might just be a custom job, as long as you keep the center of gravity closer to your body and up, it'll work. If you ask any adventure racer, which it looks like that picture could be of one, he/she might be more experienced in carrying a bike.
Like Randy says, most people that I see carrying weird and heavy, sometimes very heavy loads use packframes. If you do any hiking in NE's white mtns, the AMC volunteers who pack things in and out of the huts use packframes to bring stuff down and back. I've seen them hiking on the trails before with this huge honking loads..
