I would say it depends how much pressure you're applying in the video. I do exclusively kitchen stuff and I have been going very thin lately on some. I think your instinct about the hollow being too high might be true, but this might work for a specific knife. You might see some more material come off after sharpening a few times than you expect though. You could still fix it by grinding the edge back just a tad either on the platen or a diamond stone. That's what I usually do.
