Honestly, this is really just a better and clearer naming convention for Windows 10 21H2 update, because consumers have no idea what the fuck "Anniversary Update" or "Fall Creators Update" or "20H1" or "build 19043.1052 with Feature Experience Pack 120.2212.3740.0" or "KB5004476" even means, which can make troubleshooting hard. They're just taking a page out of Apple's book and continuously updating everyone to new experiences with clearer names, so every 6 months or year, you'll see a "welcome to windows 11.1" or "Welcome to Windows 12" update as they make minor or more major frontend and feature updates.
