If you look at the foundations of the OS the pattern becomes clear. They release a concept of an OS, but its half baked and not implemented well. So they fix it and rebrand it, and that’s the “good” version. 95 became 98 ME became XP Vista became 7 10 became 10 - they broke pattern by wanting to stay in a perpetual 10 state and keep updating it (which is why it was around 10 years). 10 was not good when it launched and took years to fix it, essentially becoming its own replacement.
