I've no idea. But I definitely saw it before Obama's release of his long form. I assume Ms. Coats came across a discussion of the issue and realized her long form might be useful as a specimen of what a Hawaiian long form of the time period looked like. It and the Nordyke twins's are not the only Hawaiian long forms to have been posted, although the Nordyke example is the closest in terms of time (and now evidently place as well, shooting down the nutcases who thought they caught an anachronism in the hospital name).
At this point, anything without a clear provenance that has no connection with Zero’s peeps is suspect.
Something that someone posted on the internet means squat, basically.
