To really cover that would have been a sidebar as long as the video. But they did mention the greater casing tension at the same pressure in a larger tire, which is the root cause of the rolling resistance you mention. Just don't forget that you'll get a worse ride quality from the wider tire at the same given pressure for the same reason. There is still no free lunch.
