Truly omnidirectional omniwheels?

I originally thought the same thing but I think he means that they wouldn't move if the driveshaft isn't rotating.

That's true of any wheel, so I don't really think it's a valid concern about omniwheels in particular.

You can't have the full wheel rotation coupled with the roller rotation to move omnidirectionally if the full wheel can't roll. That's the point there.
