The Guru is indeed very generous; see how stubbornly he persists with you. He knows your potential and also knows that at least theoretically you understand his teaching. By repeatedly hammering away at the teaching he wants you to get stabilized in the 'I am', for only then do you stand a chance to transcend it. He is constantly urging you or trying to push you into the 'Turiya' or fourth state. This he does tirelessly and relentlessly with anyone who comes to him and in whom he senses a genuine seeker. So, after expounding everything, he says: "Now that you have understood everything, just be."
