I am not sure if you are being consistent here.  Earlier you said you said
you identify yourself with a stream of thoughts (not a single thought).  If
you are identified with a stream of thoughts then you can't simply say one
brain is in Moscow and one is in Washington and that is as deep as it goes,
for you must consider the first person continuum of experience and what
they can predict about where their consciousness will take them.

You agreed if you were instantly halted, taken apart and rebuilt again
(even with different atoms) from your own perspective nothing would have
skipped a beat, your stream of consciousness continues right where it left
off.  But when you are taken apart and two copies are created at two
locations your stream diverges among two paths, which gives rise to true
unpredictability in the first person perspective.
