You’re right not to feel a ‘blow to your immortality’ should that happen; but consider an alternate story:
You step into the teleport chamber on Earth and, after a weird glow surrounds you, you step out on Mars feeling just fine and dandy. Then somebody tells you that there was a copy of you left in the Earth booth, and that the copy was just assassinated by anti-cloning extremists.
The point of the identity post is that there’s really no difference at all between this story and the one you just told, except that in this story you subjectively feel you’ve traveled a long way instead of staying in the booth on Earth.
Both of the copies are you (or, more precisely, before you step into the booth each copy is a future you); and to each copy, the other copy is just a clone that shares their memories up to time X.
