It's a theory and a plausible one, but I'd be a bit nervous about the more positive phrasing used earlier especially as I don't recall people specifically mentioning equipment changes etc. There are a few other hypotheses (from human intervention to the system being scheduled to "self clean" on seat assignments (ineligible, unconfirmed bookings etc) every x weeks or even the system automatically aiming to offer gold seats to golds making new bookings and identifying ineligible assignments then) that might just as well be correct I think.
