Whether post-duplication-machine or post-many-worlds-duplication, "I"
refers to the person having a subjective experience.  Post duplication, we
both agree that the persons diverge in either scenario. So there are two
first-person experiences, but we can refer to *THE* first-person experience
of either person: i.e., what it's like to be Moscow Man or Washington Man.
What it's like to see the dead cat or the live cat. "I" see a dead cat. "I"
see that I am in Washington.

The reasons you are giving why they are not equivalent only bear on the
third-person perspective: the description of the bodies, and how we can
refer to them.

The reasons I am giving why they are equivalent bear on the first-person
perspective: the conscious experience of the person going through the
many-worlds or single-world duplication. I have been pretty clear on why
they are equivalent... consciousness supervenes on physical brains
(assuming computationalism), the physical brains are duplicated in both
scenarios, and they diverge post-duplication (eventually, if you insist).
>From *THE* first-person perspective of either duplicated person, those
scenarios are equivalent.

Since first-person is what is relevant to Step 3, my explanation of why
they are equivalent is what matters, not your third-person explanation of
why they are not.
