Its the opposite. What he is talking about is images based OS, like Ubuntu Touch is doing it, also the Steam Deck and stuff like CoreOS. I think Android and ChromeOS are also doing that. Its not a bad idea in general.
The core operating system is a single read-only file (ROM, as in custom ROM on Android) and all the user files and customizations are on a different partition or such. Since the core system is fixed you can just swap it with a newer ROM when updating (and also go back to the old one if the update fails somehow.).

Can you explain what image based OS means?
