Why is UK escalator etiquette the same as in the US?

I’m an American living in the NYC area, and I’m planning a move to the UK in the next couple of years. I’ve been trying to do some research on day-to-day life in advance so that I don’t look like a total noob when I start living there.

Obviously one of the big differences between Brits and Yanks is the left-hand traffic vs. right-hand traffic. From what I’ve gathered, most bidirectional traffic flows—driving, cycling, walking—and their associated rules are essentially mirrored from what the norm is in the US.

However, unidirectional traffic flow is tripping me up. Apparently escalator etiquette in the UK dictates standing on the right and walking/passing on the left, which is identical to how it’s done across the pond. Is this the same for moving walkways (like those in airports) as well? Why is this not “flipped” the way other flows of traffic are? Are there any other common elements of locomotion where the UK and the US share a similar convention?
