My disagreement was terminological, not conceptual.
There is a teleporter. You step into part A and you will disappear, and step out of both part B and part C separately. There are now two of you. These two do not possess any special telepathy or connection, but both are you, and you may care about the outcomes for both before you step into the teleporter, and this may affect whether you choose to do so.
Duplication is not a process where you will end up as ‘one of the two, but unclear which’. Duplication is a process where you become two entities which are not changed by the process. You become not one, but “both, separately.” The ‘separation’ means that the two do not share observations directly with each other (though an object entering the same room as both could be seen by both from different angles).
