Correct. Movement is going from single main track to multiple main track. The way the signal system is setup at Shed 10 for eastbounds is for diverging movement to route you main train to main track one. Main track to main track 2 is "straight rail".

The signals will probably be the same. We had the same situation at CP RV005 Magnolia in Oakland. You just have to be prepared to take the slower route, until you can visually see that you are routed through the faster route.
