My guess is that it runs as a sort of "batch" process based upon a period of dates, rather than flights as part of a specific itinerary. I've noticed that all of my flights within a given time period will post at once (say 3 out of 4, with the 4th being the return leg of the second RT ticket), and then the final leg posts 1-2 weeks later once the next set of dates processes.
