Interesting. It sounds to me like Charlesworth is kidding with him but I can't work out how long he was actually waiting for a response.
This reminded me of a somewhat comparable incident the day before the landing, when the crew woke up early from their sleep period and no one heard them calling for a long while. Except for Yaw, who didn't mention it. In the end it was FIDO who confessed this to Flight.
https://apolloinrealtime.org/11/?t=069:23:42&ch=50FIDO (Jay Greene): Flight, FIDO. Yaw says he heard them. He says he heard them call about three times.
Flight (Glynn Lunney): Yaw, if you heard that, why didn't you mention it in the room?
FIDO: Yeah, we should have.
Flight: Yeah!
