This is from Dave Meltzer. Keep in mind he doesn't know everything and speculates sometimes, but he does have contacts within the organization and consistently gets the drop on stuff.

The story behind Lesnar vs. Orton was to create a scenario where nobody knew where reality ended, and preferably where people thought Lesnar was breaking the code or script.
Orton wasn’t told until he got to the arena, as he was planning for a usual main event. He was told when he got there that he was not going to have a normal match, and that the match wasn’t about going back-and-forth and keeping both men strong, but about making Lesnar stronger. The original idea was to be a total destruction for Lesnar, where Orton would be on the ground bleeding. It was supposed to look like Lesnar “went against the script” on him and hurt him. There would be confusion and the match would end, with Orton seemingly concussed and the referee stopping the match....
There will be people denying this most likely, because they have to, but Orton was told that Lesnar knew how to graze him with his elbow to open up a cut without hurting him and was told that was what would happen in the match. As it turned out, Lesnar elbowed the hell out of him, and threw some stiff punches, and Orton was bleeding like crazy from a cut that needed ten staples to close. Orton stayed down and was acting like he was knocked out, as he was supposed to. Medical personnel and the referee acted confused, because they were. I don’t know this as a fact, but I believe the referee knew going in that Lesnar was winning, but if he did, was given a different finish, because the fact Lesnar was going over was not kept secret...
One person noted that Orton was told to do it, but wasn’t expecting it to be the way it was. He wasn’t going to complain publicly about it but also was never going to do that kind of a favor again and wasn’t particularly thrilled by it.
