I don't see anywhere on that PDF that the paper was edited by someone at NTID. how did you know this?
I went direct to NTID to see what they had to say about SEE and evidently, not a hell of a lot.
But overall in my research, most people who use SEE don't use it properly which kinda defeats its purpose when the intent of SEE is to demonstrate visually the morphology of English language, particularly grammar.
Found this page which has people commenting on SEE and what they think of it:
Using SEE (Signed Exact English) | Eh? What? Huh?
