The reason is simply that, in the multiple worlds interpretation, we do survive—we just also die. If we ask “Which of the two will I experience?” then it seems totally valid to argue “I won’t experience being dead.”
So it basically comes back to pattern-as-identity instead of process-as-identity. Those of me who survive won’t experience being dead. I think you can reach my conclusions by summing utility across measure, though, which would make an abrupt decrease in measure equivalent to any other mass death.
