As far as I know, Planet13, Matt never said this: "that if you made changes to your site, then they would be noticed the next time your site was crawled by googlebot and the index changes would take place as they normally do." JohnMu implied that in a thread forum thread though he also mentioned that he was not necessarily referring to any particular update. Matt later said on Twitter that they don't run the Panda algo all the time, so putting all those pieces together went something like this: John said that in general, changes we make get noticed on the next update and possible serps return came if warranted, so we all assumed that would be the case with Panda as well. We assumed wrong (or John mislead us, intentionally or not). Matt's tweet let us know that they only "run" the Panda "stuff" (call it whatever you want) periodically. We don't know how often. Every few days? Weekly? Monthly? Every 3 months? Every year? Who knows... In addition, we know there have been a couple of new Panda rollouts since the first, but they seemed to only trap more sites, rather than re-evaluate the ones already snared. We are all waiting for that "re-evaluation" Panda to be run. Not sure it ever will be.
