The page you cited messed up the terminology - it should be "non-quota immigrant visa", not "non-immigrant quota".
"6. NON-QUOTA IMMIGRANT VISA
- This type of visa is granted only by the Office of Immigration Bureau in Bangkok to aliens who are domiciled in Thailand having as evidence valid permits to re-enter the Kingdom. Applicants shall submit their applications together with the Certificate of Residence directly to the Immigration Bureau in Bangkok."

So yes, this does refer to permanent residence (whenever immigration says "residence", they're talking about PR).
That is from the second of two paragraphs separated by the word "or". The OP was asking about the first paragraph, which did indeed mean PR.
I imported all of my household effects when I came here on an OA - basically a container-load. The shipment was subject to duty, but that only came to about 20k baht, which was less than it would have cost just to replace my espresso machine. My employer paid for packing, shipping, and delivery as part of my retirement, so for me it made sense - for those who need to pay all the costs themselves, though, the math could be very different.
