You have to stop at crossings yes, and it makes sense. Usually when there's a red light in one direction, the one perpendicular to it will have a green light.
Dublin is similar to the UK as far as I could tell, and honestly it felt like one of the worst design of traffic lights ever. Waiting for 2-3 minutes on a red light is pretty common, and green only lasts for 20-30 seconds. It's an absolute disaster for pedestrians, and as a result everyone jaywalks like crazy. I would say other countries have this right, even if drivers do have to give way to pedestrians immediately after a turn.
