OK, then if he flew to Moscow he would be the Helsinki man too, and if he
used a Star Trek style transporter instead of a airplane he would still be
the Helsinki Man, and if the transporter sent him to both cities at the
same time he would still be "The Helsinki Man". So you tell me, using logic
and your definition how many cities did "The Helsinki Man" see?

Fine. If that's what you mean by "The Helsinki Man" then in Bruno's thought
experiment with the duplication chamber and using the exact same reasoning
the probability The Helsinki Man will see Washington is 100% and the
probability The Helsinki Man will see Moscow is 100%. And yes yes I know,
each copy will see only one city, but if the definition of "The Helsinki
Man" is the one you give above, "the continuity of his memories", then it
is irrelevant how many cities each individual copy sees.
