I don't think it's supposed to be taken literally. Even keeping a pot from spilling for hundreds of years would be a challenging task, and everyone can see that. It's more so a "spiritual successor", somebody has been stewing this stew, largely never disturbing it and restoring it when it inevitably had a "malfunction". Much like you don't call your computer a new computer when it crashes and needs a part replaced. This runs into the ship of Theseus problem though.
