How do settings overlap in Lightroom?

Hello everyone, thanks for reading.

Let's say I decrease the saturation of a photo by 90.
If I then select a specific area using the mask tool and increase the saturation by 90, will the final result in that area be the same as before any changes were made?

 

And if I reduced the overall saturation by 90, then selected with the masking tool, for example, a yellow jacket. Then, proceed to the yellow slider and increase the saturation by 90.
Will the yellow components of that jacket be the same before making any changes?

No, the result in the appropriate areas are not the same as before without any changes.

The masks are local adjustments based on the global editings that has been done before.
