If duplication was not involved then why on god's green earth were you
talking about the goddamn* HELSINKI MAN*?!

P can always be equal to 1, it depends on what P means, and if P has no
meaning, if for example too many unspecified personal pronouns are used,
then P has no value at all, not even zero. In the first case
BOTH the Moscow man and the Washington man got the coffee so the identity
of the mysterious Mr. You does not need to be specified and so P had both a
meaning and a value.
If one gets the coffee and one does not what is the probability (P) that "
*YOU*" will get the coffee? Is it 1? No. Is it 1/2? No. Is it 0? No, P has
no value at all because P is gibberish.
