In the (apparently controversial) interview he gave post-stage, he said he took it too cautiously on the corners in the first half and lost time there. He decided to take more risks in the second half. I've not seen all the splits, but he was reportedly the third fastest rider from the intermediate split to the finish.
Shame for him.
A bit silly though. You can't get things wrong like that at the top level and not be punished. It is a very Thomas thing to do. He doesn't have much luck. I guess when you're known for crashing, psyching yourself out about it and doing the opposite is quite believable.
