Assume that all three branches occur (two copying events).

I agree that according to the approach taken by the q-su's, namely
that one's measure is somehow distributed among the so called
computational continuations of one's brain activity, the probabilities
would be (1/2,1/4,1/4). It is a history dependent claim:

where W=wait to show the coin to her until the second copying
event. Since she doesn't know when copying occurs this looks identical
from her perspective, but the measure distribution is (1/4,1/4,1/2)
according to the QS claim. Presumably this measure distribution would
remain the same years later.
I think this is already both ill-defined and anti-intuitive.
To extend the example suppose that to counter the unfortunate
demographic imbalance in China, someone figures out how to instantly make
a million copies of Gong Li. According to the flow of measure claim, each
of these copies would have just one millionth of a normal human measure.
So these women would practically be zombies. It would not be
justified to give them equal rights since they have so much less
consciousness. This would remain true even as life experiences give them
different perspectives and evolved personalities, some of them come to
America, etc. I think this shows how ridiculous the claim is.
