I agree with this. But i found this in 2462bis.

   A node forms a link-local address whenever an interface becomes
   enabled.  An interface may become enabled after any of the following
   events:

   -  The interface attaches to a link for the first time.  This
      includes the case where the attached link is dynamically changed
      due to a change of the access point of wireless networks.

What does it mean to form a new link-local address when you switch
Access Points ? Does it mean throw away the old link-local address ?
Only the link-local address ? I don't remember the discussion that lead
to the above text. It sure does not say "throw away the old info".
