How is the descent? Can he loose another minut until the next climb?
I don't think he'll lose to much in the descent, even if he's off he should be ok in that (unless it's a hunger knock or something and he's hurting to much to focus).
It's the long run up to Sestriere that's dangerous. It'll be about 8km that are false flat to slight uphill which means others working together can probably put a lot of time into him, partially by working together.
He still has more than enough time, so unless he cracks completely (see Ullrich in 1998) he'll be in the pink later tonight, but he can't be feeling good.
