Correct, which is why I find it strange that people are trying to hand wave his statements on how he intended God to be in his comics. Especially when we're talking about DeMatteis Cosmology, not Morrison, Gaiman, Johns or whoever you want to mention. Their statements do not matter on this site for a Cosmology they're not a part of. That's the point of the split. That's why it's called DeMatteis Cosmology.
Even the statement that people are trying to point to doesn't contradict anything. The Smile being called a "place" doesn't mean it's not God. It quite literally is called God in the very next sentence. Not to mention, the Smile itself was also called the mouth of God in issue 6. You can easily read Issue 20 of Doctor Fate and issue 10 of Spectre and see that he's referring to the same thing. Especially since the Oversoul is first mentioned in Doctor Fate comic and is carried over when Hal connects to it in Spectre Vol 4.
This is also why I don't believe this Spiritual Cosmology will turn out any good. Morrison works were screwed up and can't be combined with his older or newer stuff because they let Snyder and other authors take precedence over his works. With DeMatteis potentially qualifying for Tier 0, according to Ultima, and people trying to force all of these other works into it, it's going to either create inconsistencies or outright prevent the upgrade altogether because some other writer said something different.
