ok, a couple reasons why this may make sense:
- Privacy extensions (RFC3041): The host may want to generate multiple 
addresses in order to use them in different communications (or time 
frames) in order to achieve a certain level of privacy
- Different properties of the different addresses: for instance, one 
address could be a CGA while the other address has been assigned by 
dhcp (this tow things are somehow incompatible AFAICT), and for some 
reason the hosts needs both of them

maybe there are some others...
