I dug into this deeply once working on cloud stuff, and knew the answers 
then, but, alas, don't remember them now.  It may have to do with how 
systemd differs in assignment.  But, alas, I no longer recall the 
particulars re: Ubuntu, specifically.  But, for a brief overview of the 
IPv6 local link mechanisms (with links to corresponding RFCs), the 
Wikipedia page does a decent job:
