The node generation name hasn’t had anything to do with the actual physical sizes of anything in a while. It used to relate to physical gate length, but has basically moved off of that since 1994 or so.
Instead, the International Roadmap for Devices and Systems and previously the International Technology Roadmap for Semiconductors, just gave rough guidelines of what specifications would translate to which node/generation, and the actual companies marketing their own technology tends to just give their own labels depending on what they think is useful.
