They do not reset the CBS when they do a low mileage service - it just keeps running because too much other stuff is tied to it - air filters, cabin filters, differential and trans fluids, and so on. It's an out-of-sequence oil change that they pretend never happened.

For instance, I do about 7500 miles a year, so mine was changed at 1200 miles in April 2008, at 8,000 miles in April 2009 (a year after the 1200 mile change) and it'll be done eight months later in December 2009 at around 13,000 miles when the CBS says it's due. The next change after that will be a year later in December 2010 at 21,000 miles or so. And so on.


Good explanation, better than mine.
