WUA Offline Scan returns updates not in scan CAB file

I am using the WUA API to scan machines for available updates. These machines
do sometimes have access to the Internet, but not always. So I am using the
offline scan package (wsusscn2.cab) to scan these machines. However, I have
discovered (by extracting the cab file and what's inside it) that my scans on
these machines are returning updates that aren't even in the CAB file!

Why am I getting updates returned from a scan that aren't in the CAB file,
and how can I prevent this from happening?

Thanks.

Good question. I'm sure you've seen this, right ?:

Changes to the WSUSScan.cab file

If said workstations have *any* access to the net than that would
explain why.
By " WUA API " you are referring to Vista workstations, correct ?
