Interesting take. But they could still be the same, connected, 5d space-time-whatever entity.
Your hand and fingers are still part of the same you if you do them into the surface of flatland.
You finger, to the flat landers is a circle with some quality. It moves around their space continuously, changing and growing. But if you pull it out and insert at a different place, it not only looks the same, it is the same, but discontinuous.
Same argument?
