No, it is a different way of running a half step. Back in the day the half step gave 10 or 12 usable gears with a wider ratio rear. I am sure they would do the same thing run up or down the rear and then use the front to set their cadence.
I feel that going up or down each time in the true progression of gears is a waste of shifting, once up to the speed you want to ride at, adjust the gearing to be a comfortable pace.
