In that case you would receive a new prefix not colliding with the previous one. In the prefix assignment perspective, this new prefix is just a new delegated prefix you should use for numbering you links. So the algorithm would use both and you’d get one prefix per link for each of them. When the previous prefix gets removed, old assigned prefixes are removed too. PA is just a general purpose distributed numbering algorithm. The way you handle lifetimes is out of the scope of PA. But it surely is in the scope of HNCP (ietf-homenet-hncp). HNCP attaches the preferred and valid lifetimes to each delegated prefix, which are in turn provided to the hosts by the mean of RAs. In the make-before-break case, PA numbers the links with the new prefix before removing the prefixes associated with the old one. It let hosts renumber gracefully based on preferred lifetime values.
