Notice that this applies to fully deterministic synchronized uploads with
fully identical input, or nondeterministic and/or not the same input with
trajectory forcing, or heavily instrumented flesh people with trajectory
forcing by invasive nanoware (which basically forces them to see the same
stuff and think in unison, nixing system noise and nonidentical input).
In other words, it's a highly construed example. Useful for gedanken, but
not much else. The fork is default. As soon as there's a fork longer than
specific chronon of the system, you've got two different systems. You can
fuse the fork with trajectory forcing (assuming, the two people agree to
it), and remove one copy once they're perfectly synched. Anything else
would be murder.
Many people would oppose to fuse once they've forked, even briefly. I'm
undecided on a few-second fork, but I would certainly oppose fusing after
a hour fork.
