Well, it was a raw pool feed; they might not have been aware that it was being aired. The camera was above and behind them, so they wouldn’t have seen even the little blinking light on the camera that tells you it is live.
I have a rather extensive satellite TV system, and often get raw pool and network feeds that aren’t supposed to be seen by the peasantry, or the talking heads don’t know are live (like a hot mic they think is off). Some of the stuff I see and hear at those times is just the opposite of what they say when the network puts it out.
Could the audience not see what was going on - aired or not?
