No, that is not what will happen. All mined blocks become invalid. So all transactions in them become unmined. Unless they happen to be mined in the other chain too. Perfect time for a a large double spend... Even considering an approach that might cause a reorg is hostile to bitcoin and bitcoiners.

That's not how that works. Nothing gets "unmined" The scenario ODELL is trying to describe is if no one supports BIP110 that chain stops because of so many invalid transactions on the main chain then miners switch completely to BIP110 and mine literally tens of thousands of blocks faster than everyone else can mine a single block on the main chain. I hope I don't have to describe how improbable that outcome is.
