You did not watch the video closely - it is a matter of scale. There is an exactly equal amount of empty space! It appears between each pair of wire. The other style could be claimed as inaccurate, because they have all of wire one wound tight, then all of wire two wound tight, the a large gap - which is not what Marko's toroid map describes. It's all experimental phase - there is no official method of making the coils, so long as you have 1/3 wire one, 1/3 wire two, and 1/3 empty space.
