I don't think Facebook ever "forgot" what I said, rather it was that I was reinstalling the app for whatever reason, so it really didn't have that information. That's why I asked what would happen if something similar happened on iOS.
Also note that Android's new security model (version 6+?) is pretty similar to what you described, but yes, I do believe this incident occurred on an older version.
