There are four banks of four escalators, so sixteen total. I think there's some danger in creating anxious crowd situations if an entire bank breaks down. They'll be able to shift to one that works, but as I believe I mentioned, the cross-passages at track level are relatively narrow.
There's also this issue - if there is a breakdown of either of the "inner" banks, exiting passengers will split their escape route between two options whereas if either the northernmost or southernmost bank breaks down, all passengers will head in by one.
