New versions of Office tend to support all previous, Microsoft would be stupid to not take cases as often as yours into account. The problem is providing compatibility to those using older versions, and Sunshine has already pointed this out.
However that compatibility pack did not work for me, and I ended up having to use Office 2007 to view the newer files.
On the topic of choosing Vista editions I thought this may help
