stupid Appletalk tricks

       Okay you Appletalk guys, help me out. This may be a stupid
   question, but as a wise man once said, there is no such thing as
   stupid questions, just stupid people!
       In the CCIE All in One guide, page 850, it goes over using a
   Appletalk data packet filter.
       Here's what it lookslike:
   
        appletalk access list 600:
           deny zone TopSecret
           permit additonal zones
           permit other access
   
       This is applied to a tunnel interface outbound on the router. Now
   it says if you do a ping to 410.9 (E0) to that router from another it
   will fail. Haven't tried it yet but I'll take his word for it.
       What confuses me is that there is a primary zone, and another
   secondary zone defined on the same interface as the denied
   zone, within the same cable range. So if the cable range is 400-499,
   and the interface is 410.9, and there are three zones assigned to this
   cable-range, why would denying just one zone block the ping?
       Hopefully some of you guys have the book cause I probably didn't
   give enough info, but help out a Appletalk challenged brother if you
   can!
