Yes I think this hits the nail on the head here. Saying that, I don't know how one can think that squeezing in between a moving vehicle and a wall isn't going to be dangerous; and it certainly isn't going to be the lorry which comes off worse. A couple of the people waiting were saying that is was super risky but was given the classic London response of looking at you as if you don't exist haha. Just really doesn't help endear cycling to road users at all.
They may well be selfish, but many people genuinely don't know about the risk. It's one of those things you need to say over and over again to those whom you see doing it. You very rarely get a 'thank you'. In this case, perhaps they were just exploiting the fact that the driver seemed aware of them, in which case the risk is lower, but your charge of selfishness applies more directly.
