Yea, surely no arrangement of words could really capture true metaphysics, if there is such a thing. I don't follow this story as the "true" structure of reality. Just a fun thought exercise.
And, like Crazyhorse said, this short story is a nice little meditation on the interconnection between all of our "separate" lives and existences. I definitely entertain the idea of an "oversoul" or "worldsoul" that realizes itself through a multitude of separate, yet related, beings.
