There have been careful studies on this method that concluded the results are indistinguishable from a print made with a single filter to give the same overall contrast. (I don't have a link handy, if someone cares to look it up or dispute it, fine with me *g*) Some people like it and it works for them and that's fine. I see split printing like this as just a more complicated path to the same result, though of course I will burn in areas with different filters, or even use a piece of filter material as a dodging card/wand at times.
I did tests and found I had to add the second exposure with the 0 filter it tone down the highlights. Without it they were paper white.
