Geek,
Even if you accept this explanation, if the step were to "lift the air off the surface before it separates" then surely the step would have to be located before the point of separation?

To be honest though your explanation has me confused because the definition of seperation is when the freestream air 'lifts off the surface of the wing' so effectivly you appear to be saying that you create separation in order to prevent separation
