I've never heard or read that from anyone anywhere. Yes, bearings should be cleaned and regreased. Loose bearings need that routinely and it's useful for cartridge bearings to keep dirt and water away from them. That said, I have never heard a recommendation to press out the cups until the headset has to be replaced completely.
I have had aluminum, steel and three Ti framed bikes and have NEVER removed headset cups as a maintenance procedure. The only time they were removed was to install a new headset after 10s of thousands of miles and, when the replacement time came, the cups (both steel and aluminum) came out with no problems at all.
Note, that Cane Creek video covers initial installation of a new headset. It has nothing to do with routine maintenance.
