Back in the old days of surfaces with normals only on one side, if it was facing away from the viewer, the surface was invisible. I think now that it's more used for determining toolpaths, etc.

To expand on that, in the old days, surfaces usually were single-sided (only one normal), so you had the issues with holes if the normals were wrong. Now, it seems almost all surfaces are double-sided, with exceptions I've seen being STEP or other imported files that have holes.
