Clearly the writer of the article is giving equal time to bizarre theories, which I suppose is allowed for such a bizarre book. But I'd say the second [this guy], the one with the transliteration, should have at least been described as "claims to have discovered certain grammatical rules", just like the woman claims to have hallucinated herself into the Codex world.
The stuff you find on his page (http://www.paleoaliens.com/event/seraphinianus/codex/) is not linguistics. In fact, it's not really anything but batshit. He even seems to be losing track of the fact that the "world" of the Codex Seraphinianus is not real.
It's like people who read the Hitchhiker's Guide to the Galaxy and start seriously looking for the number 42 everywhere, forgetting that it was just a gag, in a work of fiction, written by a human. It's like that except more so.
