That might not always be the case. The /64 I have is from a /48 and apparently I could have other /64s from that block mapped to this line if I wish (http://aa.net.uk/kb-broadband-ipv6-tech.html).
This could be an uncommong perculiarity of course, A&A are in the habit of doing things a little differently to other ISPs (usually to their customer's convenience; like offering fully delegated rDNS, which I've not heared of other UK ISPs doing, and refusing to implement ineffectial and false-positive-ridden content filtering attempts).
