Sometimes I think you're so intent on finding things wrong with the Nic that you see things that aren't there or at least try to overcomplicate things to turn them into problems. Nic merged the lists based on the 2005 certified lists. Whether he then took out those that had left employment (or resigned from furlough) between May 2005 and whenever in 2007 matters not other than that leaving them in would have resulted in a list with more names.
I don't know what you think Nic did, but here's what he actually did. Removed the non-flying from each list*, dole out the jobs (300+ East, then by ratios for the remainder of the active line pilots by equip/seat), put into the combined list the non-flying but still with the airline (medical, furlough, etc) while leaving out those who had severed their relationship with US (retired, resigned, death, etc).
So it doesn't matter if he updated the combined list to 12-31-2005, 12-31-2006 or when - the names of the pilots still attached to US in 2007 (employed, medical, furloughed, supervisory, etc) would have been in the same order. The difference would be in the number of people not still attached to US - making the list longer or shorter depending on the date he updated the list too. That's why the bottom active line-flying guy from each airline were still the bottom guys on Nic's updated lists.
* One thing is unclear and not explained. On the east side, the "supervisory" check airmen aren't flying the line full time. I don't know how their peers on the west side are listed on the west list but if there was a difference between the two sides that would have had to be worked out so both sides lists were comparable in listing those pilots.
In other words, updating the list to 2007 didn't help or hurt either side. Likewise, not updating the list wouldn't have helped or hurt either side.
