I know that and have used it in the past (though it only lasts a few weeks) but youtube just auto uploads with information I've set up pre-stream. No having to port it over and whatnot. It also allows the saved stream to be set to private or unlisted after the fact in case I want to edit, but still be uploaded. It's a lot faster, especially with my internet being pretty meh. And like I said, the stream itself is a bit less laggy and more stable for watchers.
