Although Obree himself had apparently never in a wind tunnel before, the benefits of his Superman and "egg" positions have long been known. For example, Peter Keen has previously reported the impact of such alternatives on Boardman's CdA as determined during velodrome testing. There is also a peer-reviewed paper about the egg position.
I felt like his clothing held the superman position back quite a bit as the front of his jersey was flapping around. Not that it would have equaled his egg position, but I would like to have seen them test the positions with a newer, better fitting, suit. Simon mentions that, and makes a guess as to what the CdA might have been in the egg position, but why not test both? Then I realized this was a bit of a commercial for Endura, and they wanted to show the benefit of their stuff. I get it, someone had to pay for all this. It's just a bit deceptive as this wasn't a true test of positions, but position and old clothing/helmets v. new.
