I remember seeing a comment about this on another sub where someone pointed out the bottom part is flooded with water, which may have triggered a failsafe to lift the mechanism in case someone is trapped in there.
Could be that it does have a sensor to avoid crushing the top car, but the safety mechanism for the flooding overrides it.

I'm pretty sure this picture is originally from a place that got flooded and caused a short.
