No abort after unsetting HOST?

Hi All,

New to procmail -- new to the list; go easy, please. :)

I'm using a recipe that I found circling around the internet which I was 
hoping would set the Seen flag on some mail as it places it into my maildir.

    :0:
    * ^Subject.*(Security Alerts|Security Events|system check)$
    {
           destdir=.INBOX.systems.logcheck

           :0c
           $destdir/
   
           :0
           * LASTFOLDER ?? /\/[^/]+$
           { tail=$MATCH }
   
           TRAP="mv $LASTFOLDER $destdir/cur/$tail:2,S"
           HOST
    }

My understanding of this is that it places the mail directly into the 
maildir but keeps going through the rest of the block because of the 'c' 
flag, moves the email to cur/ and then unsets the HOST variable. I then 
assume that because HOST has been unset, it stops processing the rest of 
the rcfile.

The strange thing is that I now get two copies of each email -- one is 
'Seen' and one is not. See below for procmail log -- it appears that the 
first time it hits the unset of HOST, it starts processing the whole 
rcfile again!
