Paul, You're generally correct but there is a problem that is called "make before break" that pretty much effects only DCC systems because of the quick acting circuit breakers. I had this happen with one of my Shinorhara turnouts that was controlled by a slow motion machine. By using the built in contacts combined with the slow motion, the contacts were closed (making contact) on both ends for an instant--just enough to throw the breaker and shut down that power district. It was solved by ripping out the factory contacts, insulating the points and gaping the frog; then using the polarity switch feature of the switch motor.
So I'm not sure what the term actually refers to, but in my case it certainly started out unfriendly! But like anything else in our hobby there are solutions!
