I see no difference from this "1-indeterminacy" thing of yours and plain old fashioned indeterminacy, either way you can't always know what you will see until you see it and you can't always know what you will do until you do it, this "1-indeterminacy" brings nothing new to the table.

And given that you will be duplicated you don't know who you are talking about when you say "I will see Moscow and I will see Washington". This formulation relies on the usual situation in which 'I' refers to a body that has continuity in spacetime and corollary memories; but this situation doesn't hold, ex hypothesi. So the new indeterminacy is that there are two bodies that have equally valid claims to be John Clark. The referent of "John Clark" is uncertain.

I can agree. Still, if we distinguish the 1-John Clarks, from the 3- John Clarks, we might say that the referent to the 1-John Clark makes sense, like in "Oh I am the one copied in Moscow".

It is precisely the referent made by the 1-John Clark to the 3-John Clark which becomes uncertain, and that is indeed the 1-indeterminacy, which grew along the step of the reasoning.

By moving on the next steps, John will perhaps see the point eventually.
