Update downloaded but "not needed"

On my Vista PC MS Update downloaded 9342133, the update for Excel 2007
within Security Update MS 07-023 KB934670, but then did not install it
and described it as "not needed".

All others identified and downloaded in the May batch, including the
Office and Word updates, were installed.

Why would 9342133 be identified and downloaded if it was not needed ?

MS Update under XP was much easier to monitor and control I feel.

A manual update of 934670 (within 934233) worked and now 933688 of 18
May explains the oddity - the detection logic has now been changed.
