nested adjustment layer

I was examining an example file and found this. Is this an adjustment layer applied on an adjustment layer? What is this and how do I make it? I tried to apply another invert to the nested invert, but that did not work.

The lower adjustment layer in your screen shot is clipped to the layer below it, so it will only apply to that layer. You get it to do that by option-clicking (Mac) on the line between the 2 layers. Other than that, the adjustment layers are just stacked.
