AFAIK it works the same with DL. If at the end it would mean a passenger wouldn't get their choice, purser comes back and lets passenger know either they must go with what selected or choose one of the choices that still are left.
I've seen that happen twice. In both cases the passenger understood. One they went ahead and kept the pre-ordered selection and one went with one of the other remaining choices.
