Both have equal claim to being "you", but each copy feels that it is
the real "you". This translates to a 1/2 probability of finding
yourself the copy on the left or the copy on the right. This is a
*subjective* probability, an illusion if you prefer. It is what is
supposed to happen in ordinary life under a multiverse model of
reality: when you toss a coin one version of you sees heads and
another version sees tails, but you have the illusion that you
"become" one or other version with a 1/2 probability of seeing heads
or tails.
