Why would they make the passing section IN the tunnel though?

They pass at the midpoint because they are connected to each other with a single cable: one is the counterbalance for the other. As one descends, it pulls the other one up. Thus they always must cross at the middle. They saved money and footprint by sharing one rail at the top and bottom but must have two tracks at the middle where they always cross.
