He explained how he thinks the Torah was written, and by whom. He then added in apparent qualifiers to pacify Kanoim. However, he left room for what he wrote earlier and at other times.
A “narrative depiction of a deeper truth” does not mean standing near the mountain and directly hearing Hashem speak $mdash; what the Rambam calls the biggest, unrepeatable, and most essential miracle experienced by Am Yisroel.

He believes that the Torah is meant to be. This is in line with what he clarified elsewhere, that everything added became part of the Torah since they were put in through Divine Inspiration. They were meant to be added in.
He believes in interpreting the Torah only by using (or playing with) the built in methods. This is the typical Orthoprax ideology. Halacha must be kept because that keeps the people.
I’m not sure to what extent he believes in Nevua. Calling it the ‘encounter between God and the people of Israel’ sort of washes that out.
