If you add a morph to another morph then you need to delete it.
opening in world is essentially adding the morph to the paste up morph the represents the world.
If the morph is not known by any other morph it will be gc'ed. But there are a lot of ways it could be known, not only as a submorph. Local methods for deletion might also be removing those extra links.
So to answer your question. In some circumstances deletion may not be necessary. Usually it will always be sufficient.
