The cuttings from your cuttings are still part of the mother plant, since there is no other genetic material involved.
The mother plant grows a branch. You take a cutting. The cutting grows more branches. You take a cutting from the cutting. The cutting from the cutting is still part of the mother pant as this cutting grew from a cutting that was a branch from the mother plant, meaning the cutting from the cutting is still the mother plant.
Hope this helps,........
