When you have multiple identical gates in a logic chip, to simplify routing you swap them around on the PCB and the schematic gets updated.
Also, for programmable logic, it's a must. If you have 1500+ pins, chances are some nets are going to be crossed somewhere!

on-the-fly pin swapping
What is it (sort of obvious) and why would you need it?
