Yes there is physically only one operational track when your jeep is faced w/ the three door options (future, treasure, youth), and then physically only one first room that you enter (when you are admonished not to look into the eyes of Mara but you do any way and all heck breaks loose). BUT, in the entry w/ the three door options they move the side walls and the header piece above the doors just before your jeep enters to change up where your track appears to be heading. Due to the shift in wall positions the stationary track can appear to be going into to the far left door, the middle or the far right. Then once inside the door, they use scrims, lighting and sound effects to turn that space into which ever room is needed to synch with the door way. Does that make sense. You can google it and find people who have created animated models to show you how it works.
