The difficult case here is when different methods are used to assign 
addresses _from the same prefix_
This case is complicated because different methods can assign the same 
address and SAVI needs to be able to determine which is the winning method.
So, while i agree with you that it is fairly common the case where 
multiple address assignment methods are used in a given link, i believe 
that the case where multiple address assignement methods assign 
addresses from the same prefix is much less common.

I guess we need to make the distinction clearer in the document.
