The article lists Mongolian US embassy address as "constants.stuffy.activism", except the map they link to gives me the address "indoor.sheepish.blues". How can it be an address if it changes with time?
It doesn't. It's a grid system with 3 meter squares, each one having its own trio of words. Move the point 3 meters in any direction and you'll get a different one. This allows much more precise and close together addresses, down to the entrances of doors or gates.
