Of course there's an asymmetry. Sometimes it is an asymmetry observable
only by others, but so what? If the original remains awake during the
operation, he can be in absolutely no doubt that he is the original. The
duplicate *must* be in doubt, because his situation is radically
discontinuous in ways the original's isn't.
The situation reminds me a bit of the asymmetry in special relativity,
where the twin remaining on earth objectivity ages faster than the twin
in the starship, because the starship underwent an acceleration, a
discontinuous change of state.

He would be right.

But then after a moment's thought, and a look around to see that he is
in the compilation vat or receiving platform (or on the Moon, as in
Budry's great novel ROGUE MOON) he'll realize he's mistaken.

Untrue. The twin in the starship might feel no different from the twin
back on earth, but a look at his circumstances will quickly set him
straight (if he's honest).

Indeed, which will raise interesting issues for therapists, but in one
case this thought will be recognized as an error.
*This has nothing to do with whether the copy IS NOW (for a moment) an
exact duplicate, another "you", etc*. His history is different, and this
can be proved using instruments, appeals to witnesses, etc.
