expire inventory - question on number of objects examined

What does the number of objects examined during inventory expiration
include?
The following is a sample of the messages I received today when inventory
expiration completed:

09/12/2000 13:39:57      ANR0812I Inventory file expiration process 121
completed:
                          examined 40702 objects, deleting 573 backup
objects, 0
                          archive objects, 0 DB backup volumes, and 0
recovery plan
                          files. 0 errors were encountered.
09/12/2000 13:39:57      ANR0987I Process 121 for EXPIRE INVENTORY running
in
                          the BACKGROUND processed 573 items with a
completion state of
                          SUCCESS at 13:39:57.

I am concerned because "examined 40702 objects" is such a low number if
"objects" is the same thing referenced to at the completion of a node
backup.  For example, a single node backup alone last night completed with
the following messages:

The number of "objects backed up" for this node alone is over 20,000.  I
know that many more files have been backed up for other nodes as indicated
by the following portion of output for one volume of a particular node
using the QUERY OCCUPANCY command:

How can I be sure everything in my TSM database is being examined for
possible need of expiration?
