Upon further investigation this is pretty much a non-issue.
Although the subscriber still shows listed in the Subscribers list for the domain, and is included in the count for the individual Mailing List, if you go into that specific Mailing List and choose SUBSCRIBERS they will no longer be included. So, the #UnsubscribeLink# is indeed removing them from the Mailing List, just not removing them from the count and from the master Subscriber List for the domain.
Close enough to W.A.I. for me.
