How would the kill switch help to prevent a backfire?

When you key off, the computer stops the spark and fuel simultaneously. With a kill switch, if wired properly, it kills just the injectors, keeping the spark going, igniting any left over fuel in the last few revolutions before the engine comes to a complete stop.
