I think he is explaining on hand use if air is not available to users.
The 3000 Trizact disc does eliminate the need for multiple steps (1000, 1500, 2000, 3000, etc.)
That what make the disc so unique. Even other sanding systems, you sometime still need to climb the ladder to perfection. 3M has eliminated the multiple process and made it simple with a 2 step sanding setup.
