>This certainly surprises me; am I missing something about this concept?

If you read the topic "Using Bands Inside Areas" under "Creating Bands" it 
says:

"To create bands inside an area feature, enter band sizes that are less 
than zero instead of greater than zero. For example, you could ask for 
bands around Los Angeles County in sizes -10 miles, 0 miles, and 10 miles."

That is an example of two bands, one inside and one outside of the border 
of the area, plus one that is the same size as the area to separate the 
other two.
