This tutorial is dealing with Light Tracer, not Mental Ray.
To try and answer your question, I'm unsure as to whether it's even possible to use a normal map to bake in Ambient Occlusion, seeing as a normal map varies the surface angles of your geometry and contains no depth information at all.
You can do it with a bump/height map quite easily and, of course, your high res source mesh. Is there any reason why you can't you use the mesh you baked the normal map from to get the Amb Occ bake? If you used a bump/height map to convert into a normal, just use the original bump map you made.
