If the copies are really identical then "you" feel to be in only one
place (insofar as spatial position has any meaning when talking
about consciousness)
Which it has not. We both have agreed already on this. And the copies
are identical, as bodies reconstitiuted at the right substitution
level, but they are in two different place, as they will notice when
opening the door. And the Hesnki man knows that in advance, so he
knows that (whoever he is and will be) there is 1/2 chance to see M
(or W).
because "you" really are in only one place, regardless of how many
copies are made or where those bodies are.
Exactly.

The question is will "he" turn into the Moscow Man or the Washington
Man,
Yes. And it is (and can be justified entirely with math) a non
constructive "OR".
and that depends on one thing and one thing only, what information
"he" receives.
Not at all. It depends on the entire protocol. the information he will
have will confirm or refute his prediction (written in his diary, for
all possible "he's" relevant).
