I think he is trying to say he believes that there was an actual fall from grace but Genesis is telling of this fall from grace using a metaphoric story. I think this view is also taken by many biblical scholars. I am not familiar with ancient literature but this metaphoric style of writing may be pretty common as well.
This isn't a perfect example but the movie 300/comic/legend does represent an actual event. However the event most certainly did not take place in the way it was portrayed but it did happen.
