Ah ok, I thought that was merely to keep track so it stops if goes out-of-bounds (as a failsafe) wasn't aware that it needs it as well for actual guidance.
I have a bad feeling that the ride will suffer from a lack of a live guide. That was still the thing that made me really excited about it from HateToFly's original post way back, and bummed that they were replaced by hardly-seen robots and (I presume) voiceover. That personal touch almost always makes a difference.
