The documentation there may not make it clear, but you could do things like navigate from one page to the next, and fade in the new page, from a normal full page reload, with no intermediate flash of unstyled anything.
It was part of the attempt to lock the web into DirectX and even Microsoft themselves deprecated this a long time ago. But it definitely worked. I remember playing with it. IE4 though IE6-ish had a lot of weird stuff in it to try to drive lock in.
