In this case I believe that you're wrong.

Try it and see how it WON'T work - I already did. Until you execute the
DELETE operation at least once, the %FOUND won't evaluate properly.

DOW evaluates the condition at the top of the loop, before the DELETE is
ever performed.
In this particular example, the DOU evaluates the condition at the bottom of
the loop, after the DELETE has been performed...
