I presume you mean that the world is duplicated on each toss, with
one branch showing each outcome. We are back to the dreaded
"person duplication" problem. My opinion on this is that on such a
duplication, two new persons are created, so the probability that
the original person will see either heads or tails is precisely
zero, because that person no longer exists after the duplication.
So if some aliens create a copy of you in Andromeda, then you cease to
exist as a person?
Since I might know if they gathered the requisite information, it is not
an issue.
Note: according to current comological models, space is infinite and
uniform, which means infinite copies of you exist (though very far away).
Such models make really quite strong assumptions about initial
conditions. You might well have an infinity of worlds with our present
cosmology, but they might all be copies of some bland, boring model with
no intelligent life. An infinite number of universes does not imply an
indefinite number of copies of every particular universe. There are sets
of zero measure, after all. So again, I don't think there is anything
here to concern us. Even if there are exact duplicates, they are in
principle non-communicating, so are operationally different persons.
