Split points are made to reduce/eliminate wandering. Gil's method is basically what prepunched skins (not matched drilled/punched ribs). A line was drawn on the rib/spar center line then you could push the rib around a bit as your could see the line through the hole in the skin.
If your ribs are square and straight, that shouldn't be necessary. You can drill every other hole and use an inspection mirror and light to see that you are still within tolerance for edge distance and drill the next hole. If you see the center is starting to drift, you can then manipulate the rib slightly.
I am not sure if either way is faster or slower. Doesn't matter. That is the beauty of the early kits. You just had to figure it out and do it.
