That was an old screen shot in the Guide from when the ISO was built using the older procedure. That procedure used drastically different processes under the hood and different source material from Microsoft, resulting in the more "modern" date.

The ISO built from Microsoft using the new procedure is the 22H2 GA "Retail" release from September which is fine to install from. Those dates are as you see them released on a "real" distribution from Microsoft. As you are noticing, it will update itself to the latest monthly update. 

I'll update the screen shot in the next version of the guide to reflect dates that you'd see today.
