Sorry no time to watch the video. There are couple of ways for it to be completely procedural. First is to have baked input mesh with PLA because effector time offset can work only on animated values. Second is not using clones which is not optimal because you need to use Xpresso and iterators and everything has to be real geometry, meaning no instances or clones. Third is to clone absolutely everything as shown in scene file. Another way which is probably most difficult but leaves you completely procedural is to build your own L system rig with MoSpline with geometry generation + Xpresso&Python. Not simple at all...
