The apps can't detect the update as it occurs, and may simply fail when executed. Not sure how one fails gracefully in such a case. Is there an Apple "standard" for such things?

Some people have gone the other way, and merge the two apps into the same bundle, and then make a third 'loader' app which is when gets initially run, which then loads and runs the real app based on which OS is running. This makes the app bundle larger, but handles the upgrade/install problem you are having.
