So in this theory, there is only a "main" timeline in the sense that whoever is traveling says, "This will be my focus point." and probably chooses their origin timeline. And the important timeline isn't a timeline at all but a focus point, an event that will affect all things that follow it in that timeline, which is actually a pretty common thing in timeline theories.
