I think that was what he was implying, he was just uncharacteristically terse. He must've been in a hurry to get lunch.
BTW, there is no definition of "offense", and more particularly no rule that tells us who is on offense and when. That is what makes the term "offensive foul" so meaningless in an NFHS or NCAA rules context. Based purely on my understanding of the "general usage" of the word, I would say that the throwing team during a throw-in is "on offense." But, obviously, they do not have team control.
