I'm almost positive that he's referring to the fact that everybody keeps asking if iOS6 will be an OTA update, even though it clearly states that it will be.
It's funny, people have lost so much faith in Apple that they neglect to check their website for the simplest of questions.
I take that to mean you can update wirelessly once you have it... I'm not willing to stretch that to mean one can update to iOS6 wirelessly... but, I don't really care since I installed the GM already.
