This distinction is less relevant today because since RFC4291, it's 
allowed to use ipv6 anycast address as a source address.  From the 
RFC:

    o The restrictions on using IPv6 anycast addresses were removed
      because there is now sufficient experience with the use of anycast
      addresses, the issues are not specific to IPv6, and the GROW
      working group is working in this area.

So practically there's only a single anycast concept now in IPv6 as 
well.

Special thanks to Joe Abley who pushed this through.
