Actually it was working correctly in the screenshot that Petr showed there.

It does not currently try to duplicate edge curves that are also silhouettes, it only generates "new" silhouettes for the internal parts of curved surfaces.

If you do have an example where it is not working in the 3D view, could you please post it?
