At the end of the movie [Life of Pi,][1] Pi tells us two stories. One with the tiger(unrealistic) and one without the tiger.(realistic)

I believe that he was metaphorically referring himself as the tiger who enters the forest(world) after being rescued.

Is my thinking correct? What other versions are there? can you explain me the ending?
