No.  Three options:

1. No expiry.  Only articles explicitly marked with 'E' from the
   summary buffer are expired.  Reading articles marks them 'R'ead.

2. Auto-expiry.  Only articles marked expirable are expired, but
   reading articles marks them 'E'xpirable.

3. Total-expiry.  Articles merely marked 'R'ead are expired, along
   with articles explicitly marked 'E'xpirable.

Assuming you read every article, auto- and total-expiry will
eventually expire them all at the same times.  It's just a question as
to whether you'd prefer to mark articles as expirable or read when you
read them.  I tend to use total-expiry for everything; it has
predictable behavior if I'm switching it on and off for a group, and I
understand better how it works with scoring.

Where are the articles?  If we know what's saving them and where, it
might be possible to explain how and how to clean them up.
