I guess this is just a matter of taste, so feel free to leave it as is. The reason why I suggested the change is that there are two boolean flags passed in: `genNested` and `outerCombined`. The first one indicates _what_ it will do and the second indicates _when_ the caller should set it to true, so I thought it would be good if both conveyed information in the same way.
