Functionality: Surfaces on original objects and clones will share the same surface settings. There is no way to individually select a surface setting on one surface without it affecting all other surfaces that share the same name of all cloned objects from the original. (e.g. Create a sphere, change the surface to Red, create clone of that sphere and change the surface to blue, the surface of both objects will become blue, clone a third sphere, make that surface green, all the spheres turn green.) you can not change one without changing all the other, you can not select on the individual surface names in the surfaces list to modify single instances either.
