Why did pasan switched to second addChoice method with page argument here? Please explain. From story as second argument her switched to page as second argument.. I cant figure out why!

    let returnTrip = Page(story: .ReturnTrip)
    let touchDown = returnTrip.addChoice("Stop and Investigate", story: .TouchDown)
    let homeWard = returnTrip.addChoice("Continue Home", story: .Homeward)        
    let rover = touchDown.addChoice("Explore the rover", story: .Rover)
    let crate = touchDown.addChoice("Open the crate", story: .Crate)
