When I hear some people say that all the religions are the same often what they are saying is that no belief has any enfluence over thier lives. In that regard they are "all the same."
Logically all things cannot be the same and remain coherent because they diametrically contradict one another.
But taking certain passages and applying the wisdom in them, I think, is what he is referring to.
