If someone cancels their flight (or changes to a different flight) and they already had a boarding pass then their number goes back into the system. Say I checked in and had A-14. You checked in right after me and have A-15. I cancel my flight so A-14 goes back into the sytem. Someone checking in hours later who might normally have gotten a C-group can get the A-14 that I originally had. Even though they checked in after you it is possible for someone to get a lower number boarding pass. Make sense?
