Also, it's easier to overheat the edge if you start at the heel.

Personally, I grind the primary, the secondary, then finally I split the
point.

I agree that it may be easier to overheat the edge if you start at the
heel, but with a good wheel it is not a problem for me. I rarely am
doing much more than touching up the drill using the fine wheel. Any
significant amount of grinding is done on the coarse wheel.
