In this example, the car is taking up part of the intersection (shared resource A) and the bus is taking up another part of the intersection (shared resource B). In order to get through the light, both parts of the intersection are needed, you need parts A and B of the intersection for your car to pass. Now the bus and car are deadlocked, the only way out is for one of them to back up.
