Yeah, although his point seems to be more about the more aggressive and incessant chatter that's going on now, rather than the occasional potshot. And to be fair, given the existence of the stump mikes, he brings up his own gaffe on-air at Nine, which nearly cost him his job.
Anyway, he has actually been commenting on this issue for a while now - you can read his thoughts here:

He's a very strange character, Chappelli. I disagree with him quite often, but I generally regard him as a fairly moral individual. I was just reading yesterday that he actually walked out of the commentary box the other week when the PM, John Howard entered, on the basis of his strong opposition to the govt's immigration detention policies. A guy you wouldn't want to get on the wrong side of by all reports, but you get the impression fairness is a high priority for him.
