What I described had absolutely nothing to do with overbooking.
Pax X buys the last L fare seat, not sure he is going to need it, but wanting to hedge his bets.
Pax Y, shortly thereafter, has to buy a seat in a higher fare bracket.
Pax X later cancels the reservation.
Pax Y has been hosed just so Pax X can have the convenience of covering all bases with his multiple reservations.
If I am Pax Y, then it is indeed my problem.
