The short answer is that that is what Linux/MIPL does. We haven't changed anything. The slightly longer answer is that RFCs2461/2462 describe how prefixes are advertised with a valid lifetime and that addresses take on that lifetime and can be used until that lifetime expires. RFC2461 specifically describes the case where a laptop is unplugged and is entitled to use its previous address when plugged in again. The default value for lifetimes is 30 days and infinity is a valid value.
