That's kind of odd. It's a very different kind of climbing from natural rock, or even gyms. I'd expect it to be either fairly easy or literally impossible -- the required holds either exist or they don't. It will be far more repetitive, and is a test of bravery and endurance rather than skill.
This will be a live event. The stakes are high so I expect it to do well. I also expect he already knows he can do it easily as he will just be repeating the same section over and over for most of it.
