Infinite Worlds originally appeared in GURPS Time Travel (by SJ and the eminent John Ford). At that time neither GURPS Cabal nor Horror(3e) had been written yet. AFAIK at that time Ken Hite had not yet written a GURPS book. Later the Alternate Worlds books were published in support of the IW setting (primarily). However the idea that IW was a meta-setting that could conceivably connect any GURPS world had yet to be conceived. That was an innovation of 4e. Pulver wrote the IW chapter in the book, but Hite wrote the iconic character stories and will pen Infinite Worlds.

Could someone please explain what the common elements of these settings are? I guess that the Qlippoth, the Anunnakku and Professor Headley's 'ancient ones' are all the same. I guess that the parallel earths are all aspects of Assiah, in the Cabal's terminology and that they all connect to the same Atziluth (I'm not sure if there are parallel versions of Briah and Yetzirah, but I suspect not, at least not in the clearly seperated manner of the alternative material worlds).

Knowing Hitey goodness, I suspect he will leave a healthy amount of mystery and possible connections, in defining the metaphysics of IW.Your interpretation seems to be a pretty good default, however.

Also, does anyone understand the bit in Iotha's character story (page 316) about the City of the Wall (is that Berlin?) and the 'grey men' (is the reference to them making rifles on the moon meant to be taken literally?)

I agree, the City of Walls is an implied Berlin. The grey men are probably "grey" aliens and the moon is probably literal.
