AFAIK, it is, tho not due to any particular fancy cleverness in pan, but 
rather, due simply to the way nntp works (cleverness in the protocol).

What it does is get the post sequence numbers that are available from the 
server.  Since it tracks the ones it has already has, it skips them as it 
makes its requests.

Just don't delete them, and ensure your expiration settings are set so pan 
won't try to delete them.  I'm not sure about get N or N days headers, but 
the get all headers function, at least, forgets what it has already seen 
if the header has been deleted, so it can be used to recover, if you 
accidentally delete a header you decide you actually want. (I have to do 
this occasionally, unfortunately.)
