So, assume 1600 release. CA gets rerouted into an extra day. As soon as he is scheduled to release later than 2000, he gets 23L8 pay for the duty period and all following duty periods. So block + m/u for the original last day and new last day.
Same setup for a reserve…the original last day is LC so the trigger is not met unless the release (adjusted for base time) interrupts an X day. Only the new last day interrupts your X day so you get block + m/u for the last day.
If your reroute on the original last day goes past 0000 base time for release before the break in duty, then 23L9 is exactly the same as 23L8.
This might be what the discrepancy is. Our release, after timing out in the outstation, didn't interrupt an X-day (original release was 2145, RR'd release was 2200. I'm rounding but that's close enough), although the trip was originally a 3-day that turned into a 4-day with us operating back to ATL on my X-day.
