For anyone who's very familiar with the Jordan quotes, he wasn't in the habit of lying. He gave a few "Aes Sedai answers", but no straight lie (answers suspected of being wrong mostly sound like honest mistakes on his part or badly reported non verbatim answers. Some of those he corrected in later Q&A). He simply RAFOed stuff a lot, even RAFOing stuff he didn't have to because he knew we read tons in those RAFOs and it amused him.

Basically, RJ really loved the WOT theorizing phenomenon, but as far as we can tell, he played fair with us... that is respecting the "Aes Sedai rules". By the time he had his blog, and later during his disease, he became a lot more talkative, giving some answers straight out he had long RAFOed.
