The confusion is understandable, considering those grinding with a large-grit wheel remove a lot of metal quickly and in so doing leave a "finish" of very deep scratches. But in grinding, scratches are just the aftereffect; quick material removal is the goal, especially when working with heat-sensitive metal like stainless steel.
