I agree with you in principle about not blocking the box. But in practice it's not always like that. Sometimes the actual light timing needs to change. Sometimes the roads need to just be different than they are to prevent bottlenecks, which is a pretty expensive fix
Sometimes you roll up to an intersection, and every time the light turns green, the direction you're trying to go already has all lanes filled by another approaching direction. Every time.
