The master plan only planned the mid-field terminal which the current auto train is planned to go there. And, afterall, digging a tunnle under the busy taxi-way sounds prohibitive for me.
IIRC, when they built the satiellite terminal, some of the gates (15-17?) were closed. They should be able to dig a tunnel back then.
