How does Orlando save Oliver's life?

Oliver tells Rosalind that while he was asleep in the forest, Orlando happened to come across him sleeping under an oak tree. A large green snake had curled herself around Oliver's neck and was about to enter into his open mouth. When Orlando arrived it uncurled itself and crept into some bushes. Under those bushes a lioness lay waiting, her udders nursed dry, thereby making her ferociously hungry. Orlando, having seen all this, approached his older brother.

Orlando almost left his brother sleeping there but instead chose to battle the lioness and kill her. Oliver woke up at the noise of Orlando fighting and realized that his brother had saved his life. He immediately regretted ever trying to kill Orlando. Orlando took Oliver to the Duke's cave and made sure his brother received hospitality. Orlando then fainted from loss of blood and Oliver had to bind up his brother's arm. Once Orlando woke up again, he asked Oliver to take the handkerchief to Rosalind and tell her the story. Rosalind faints once Oliver presents her with the handkerchief.
