If you want to loiter on a cliff with the pope you better be ready to move in perfect circulation with him. The pope is wearing really heavy robes and it's hot up here on this cliff, so you both need to walk in circles to keep cool.
This circulation wouldn't have to even be happening if it wasn't June (じゅん). The cliffs are so hot in June, and in any other month the two of you would have just sat down and had a chat. But in June you have to do this weird circulation dance.
