Because they booked GTY rooms.
If you aren't familiar with GTY, this is a good explanation.
What is Guarantee Status?
Guarantee Status means that when you book a particular category, Disney is not able to assign you a stateroom number at the time of booking. As you get closer to your sail date, Disney will assign you a room number. You can end up in any stateroom that is in the category you booked. However, at their discretion, Disney may upgrade you. It's not necessarily likely that you'll receive an upgrade - but it is possible.
If you try to book a stateroom and you want to be next to or near (or maybe, even - far away from) a particular stateroom, you may wish to book a the next highest category so you can confirm a particular stateroom number where you need it.
This is just like any other
Disney Cruise Line booking. There's nothing special about; other than the fact that you won't know which particular stateroom you're in. All the normal deposit, change and cancellation policies will apply.
On some confirmations/documentation, you'll see this referred to as "GTY". That's an abbreviation for Guarantee status.
Guarantee status is similar to a room assignment. Suppose you book category 8A. You go to pick a room, and you must select "guarantee status". You would then talk about this as "category 8A, guarantee status".
