Bob, I'd say that because the 'exception" is so specific (2 1/2 in starter pieces less than 12' long) that the intent was also specific and, in addition, because they used starter pieces as a criteria they mean only for branch lines. I think the handbook commentary for 9.3.5.3.3 suggests that it is a gimme for this single set of conditions.
