Sure, BUT if you read the article, you'll see it addresses broken screws, broken bolts, broken drill bits, and broken taps.
As we all know, the chances of breaking either is pretty much equal.
They also give tips on keeping your drill as close to parallel to the axis of the broken piece as possible, and using a "T-Handle" in lue of a drill/driver or wrench/ratchet, to keep equal pressure on the extractor.
A read that SHOULD NOT BE MISSED!
