Unfortunately (per my understanding), that is not how it works. People can and do suffer from USCIS mistakes, so really, it's on us to make sure we know the rules and make sure we do not benefit from inadvertent mistakes.
I'm happy to be coorected, but my understanding is that the general provision is 5 years. Period. Not 4 years and 11 months. Improperly obtained immigration benefits have been reversed, including citizenship.
I feel for the poster, but if I were that poster, I would REALLY endeavor to get that fixed ASAP.
