I'm sorry that you don't understand the meaning of that.
i absolutely do know the meaning, since it's all i use.
it's you who doesn't understand what a non-destructive workflow means
A non-destructive workflow means you can *undo* and then *redo*.
That is not a reversible function.
For example, you can add sharpening with a high pass
sharpen tool to an image, save it as a JPEG, send it to
someone else, and they can use a blur tool to reverse
the sharpen.
If the sharpening is done with UnsharpMask that cannot
be done. USM is not reversible.
