I'm going to guess he smashed his inhaler after a stage. Did a wee test and it's higher than it should be.
This seems like a fairly plausible explanation. If he smashed his inhaler during the stage then there would be plenty of video/pictures to show this. Salbutamol is short acting and drops off quite quickly within a few hours so it couldn't be blamed before the start of the stage.
Taking more than 2-4 puffs during the last hour of racing would be pretty pointless as he wouldn't bronchodilate any more. It would only serve to make him tachycardic which would be detrimental.
