The quick answer (not 100% complete) is the computerized distributor does not advance / retard the timing, the computer uses a spark table to advance / retard timing. In my way of thinking, it's like advancing / delaying when the coil actually sends spark to the spark plug. There are better explanations, but that how it works in a nutshell.
