A few things to consider. If he had turned up to all of those flights there is the exact same financial situation for the airline as if he cancels at the very last moment, so him cancelling or not showing up is not an issue. The airline didn't complain that he booked too many flights. What would be an issue is if he double-booked flights, so there would be one he couldn't turn up to at all, this would be screwing the airline and bad faith. If he had done this he would have to know he would be inconveniencing the airline. The court case didn't bring this up and I would presume if they're willing to pull out specifics like the aforementioned cancellations, then they would jump at showing he double-booked flights. This leads me to believe he never did this, so he always intended to take the flights or at least wanted the opportunity available for him to take them, which really you should be able to with an unlimited ticket like that.
