The original poster, TheAlmightyHubbard, mentioned nitrox. The quote from the original message indicates that the diver in question does NOT use nitrox. I was pointing out that it adds some credibility that the diver knows NOT to use nitrox at those depths.
I wasn't responding to your post, I was referring to the original, in which, as you mention, only the OP refers to Nitrox.
