That’s the theory anyway.

FYI, there is no one standard amount of time (afaik) for how long it takes lights to switch to green. Quite arbitrary. Especially when you also add the influence of a traffic policeman who can choose to wave traffic on in the face of a red and keep greens waiting, cars randomly choosing to jump the gun, unseen obstacles in the road ahead…
