This is not what happened according to his DS on Dutch tv tonight. Ruijgh dropped back to get a drink for himself, when he should have asked one of his teammates to do it for him in view of his position. The first big acceleration took place just as he was at the back, costing him that much extra energy just to get back to where he was before he went for the drink, which resulted in him losing some extra minutes at the end. I think we can be sure that he will have his bottle brought for him tomorrow.
Not only that, but the boy is the highest ranked Dutch rider, and he intends to try and finish even closer than his current 26th place at 11 minutes down.
