Maybe it's Levi's contention that with Horner continuing his tempo after reeling in Hesjedal, it tied Levi's hands, as was stated in the link in the OP's post, he couldn't continue on with Horner without pulling Hesjedal along. I'm assuming Hesjedal has a better sprint than the two of them or at minimum better than Levi, should they all had made it to the finish together. Possibly Levi felt he had the legs to match Horner. Horner's decision to go for his own interests after starting out as Leipheimer's lieutenant was a questionable, rather scandalous, and dastardly brilliant move. It's my guess it was around that moment that Leipheimer decided it was time for him to look into jumping ship, which he did.
If either Hesjedal or Leipheimer were strong enough to follow, they would have done. Horner attacking after catching Hesjedal is the exact right thing to do. If they catch him and then just drag him up, letting him recover a bit, then that's a bit of a waste of energy. If they've caught Hesjedal at that tempo, they'll probably drop him.
The only things that betrayed Levi were his legs. If Horner had actually screwed him over, then he would have been perfectly justified chasing him down. He was just ****ed that Horner didn't wait for him. If you get dragged up a climb and then can't stick with the guy who dragged you up it, then you don't deserve the stage.
If Horner takes Hesjedal with him, that's stabbing Levi in the back. As it is, he puts in a little dig to drop Hesjedal, as he should, and Levi is too weak to follow. No scandal, just bike racing.
