Why wouldnt they prebook seats next to eachother? Play stupid games, win stupid prizes

It probably wasn't available. Either all the clumped seats were gone by the time they booked, or it was a last minute replacement for a cancelled flight (when all seating preferences go out the window so you can just get to your destination within a week of when you'd planned to).
