AO Correction(Hack) in Blender

Normally when i add AO to the image i just used to add it with the help of a Color Multiply node.
But that doesn't gives good results most of the time because it makes the brighter areas dark.
so i came up with the Solution here.
(Shown in the image)

Here i just turned on the AO option and used an AO pass too for the node.

So i hope you will be able to understand this setup.

By this setup you will be able to keep the Brighter areas of the image bright even with the includation of the AO pass
