Allegedly there's an actual re-evaluation during the renewal. For example if you start showing up on terrorist watchlists your next renewal might not go through.
I think this is kinda true because my wife was involved in a customs incident and then was unable to renew pre check for a bunch of years, thought that was never given as a reason.
