This animation is based on an ancient story which was passed on from one generation of story tellers to the next, long before writing was developed. It is often associated with the Zen philosopy and is used by Zen teachers, although, according to my research, there is nothing that proves that it was created for this purpose.
The story is also used by therapeutic practitioners of hypnosis and in recent times pratitioners of Neuro-Linguistic Programming (NLP). It fits well with the conept that the meaning of any communication is in its interpretation by the recipient not by the intention of the person instigating the communication.
Maybe you will be the one to finally discover what the story is about.
