You thought that because Microsoft did say that. It just turns out they lied.
My pet theory is that Microsoft reconsidered this position when MacOS went to version 11. Having a lower version number must still carry some connotation of being "behind".
The actual version number for Windows 11 says it's Windows 10.
I can only imagine that the person from Sun Microsystems who was responsible for Java 1.2 being called "Java 2" and Java 1.5 being called "Java 2 Version 5.0" has since found work at Microsoft.
