Should work, as long as the name of the Person atom outside the subscene always stays the same. So it would need to be always "Person", and not "Person#2" or anything else. You may get a warning that you are referencing things outside of the subscene, which is actually what you want here, so its fine. Obviously stuff breaks, if you load your subscene without a Person atom named "Person" (or whatever name you decide on) being present in the scene.
