In the simple case of a fiber cut and repair (the proverbial errant
backhoe) you're pretty much correct. The tech splices the cable
in the obvious to fix order (typically by color code). I suspect
you could try and be lower in the color code, but in practical terms
once they get going there is not much time difference first to last.
There are more complicated cases though; consider the Baltimore
tunnel fire years ago. Restoration required running several km of
new fiber on a temporary route, and most importantly troubleshooting
if that did anything bad to anyone (e.g. put them over their distance
budget). It is entirely possible to be moved to the front of the
"I need help" queue in those situations.
In most cases, if you care about paying lots of money to be first you
have enough money to buy an actually physically diverse route, and it's
a non-issue though....
