It seems to me that differentiation is local, and spreads slowly, and that there is always going to be some remerging (but only in proportion to the chances of entropy reversing). The an atom starts in a superposition of decayed and non-decayed. Now a cat is in a superposition of alive and dead. Now an experimenter is in a superposition of having seen an alive and dead cat... now everyone who reads "Nature" is in a superposition ... but none of this affects Jupiter for a long time, it may be centuries before it has any noticeable effect, particularly if in both branches human civilisation collapses, so there is less chance of us sending things to Jupiter ... and it may be millions of years before any other stars in our galaxy are affected. Maybe as history goes on and civilisations come and go and new species evolve, some of the branches that were split by the experiment merge again, and eventually the universe gets back to where it was originally, in terms of the degree of splitting. Of course it might be a looooong time - say a googol years - before all traces of human influence vanish completely.
