From the video, it does not look like he calmed down because of the bloke behind him. He was telling that bloke that "I will carry on" when told to stop. He only calmed down because he got his way - he managed to intimidate the woman to change seats away from him.
A personal observation: I noticed that some elderly folks tend to get cranky and quarrelsome when they feel that they are disrespected.and will start scolding or audibly grumbling at strangers over trivia issues. I have had to intervene very recently on two different occasions when travelling with two different very elderly relatives after they started scolding strangers on pubilc transport. I suggest a similar mechanism is at play in this event.
