Essentially, AO maps make the lighting more correct.

Ambient occlusion doesn't necessarily occlude direct light, only ambient or bounce light. You don't have that control with the diffuse texture alone.

Baking AO into the diffuse texture is like adding black paint to your object. It's not going to affect the lighting, just the color of the object.

Putting AO in the diffuse texture has long been the only option. Now we have a relatively new and better way available.
