From my experience, not possible to induce such an error on purpose.
It must be some issue with the system itself if they allowed such double spent attempt to occur at some point.
In this event, I'm guessing they should endorse full responsibility no matter what and should pay your due.
I highly doubt anyone is talented enough to trick the system anyway.
