It might be useful with Chinotto, that has very close spaced buds. Often hard to find a good stick with spaced buds. ( I usually used very tiny chip buds ).
I have tried something similar with Microcitrus with thin angular twigs, i.e. half the twig side on so it has a face with two buds. Took Ok, but didn't always shoot well.
Maybe this has better cambium contact ?
