When you take a cutting the plant will grow more branches below the cutting. If you take the top off of an uncut plant, you will get two branches coming out of the top. Those branches will come from the highest node. The node is where the fan leaves come out from the stem. Also the next node down may grow two branches as well. I have had some plants the did this. Anyway, so then you take a cutting from each of the two stems, and each of those stems will produce two new stems at the highest node. Then you have four branches growing. Cut those four, and you will get eight and so forth. It's like a hydra if you know greek mythology.
