I was there at time when AT&T was negotiating the replacement for the V7 license with 10 of us (the 10 firms included Microsoft - the only time I can say I was in the room with Willy G. - but that's another story)​.  This work would become the System III license.

Yes, you are correct: In november 1981 Xenix ran on the Altos 8600. Once you run on one 8086 machine, the next is minor step.

Your insights about licensing match with the chart on the ‘seefigure1’ website, and help explain some things about it.
