I don't think they would confirm if your resort is closed no? maybe that happens when you confirm the computer or rep would assign you to that new hotel and offer you some price of a difference (this is my assumption) maybe give it to you gratis or discounted too.
I think they are really trying to tell people you will have a reservation spot but it won’t be of your choice like your stay at CBR gets changed to POP and you get a refund but have no say in the Change also you could go form ASM to AKL
