This does not waste any power.

The only wasted power in a mecanum is due to the friction in the bearings in the rollers.

I think he means in the sense that part of the force "cancels out" as it's applied in a direction the robot is not travelling in.

Even with a frictionless roller, you're wasting power by squeezing or stretching carpet in the sideways direction while trying to move forward or back. You could perhaps argue that this isn't being wasted "in a mecanum", but it's definitely happening because of features inherent in a mecanum wheel.
