As you continue to climb, you can continue to pick up the pace until you near the top when you can begin to hammer. I believe Jens used the metaphor that such a technique is like “rolling out a large carpet,” which goes very slowly at first but then gradually picks up greater and greater speed.
Keeping in mind that he's talking about climbs in the Alps and such, and that climbing while racing is a lot more of keeping you from maxing out effort too early than regular riding might be.
