The article needs to be updated.

There is a much simpler solution. If you run the 'union' tool on the feature class in question (so it is the only feature class in the list) and uncheck the 'gaps allowed' checkbox, it will fill in the gaps/donut holes which you can then query simply by the missing attributes.
