We have the same system, it uses GPS and wheel rotation to confirm location, and a separate system for doors called ASDO .
The only problem with the system I can see is if it is not sure where it is on the network, you can open all doors so if you missed a stop mark and stop short it will let you open all 5 carriages even if one is off the platform.
It should be a fool proof system but the blame will lie with the fool pushing the buttons.
Leaving up to the guards was a much safer system.
