Ah, okay, that fully answers my question, thanks. That makes it impossible though to apply the same technique to a single variable twice, without further tweaks (either versioning of the variables, or actually stacking the shadowing itself).
Honestly though, I don't think that's going to be a big issue in practice.

I think you didn't misunderstand it. But it might be beneficial to have a few additional explanatory words in the documentation nevertheless :)
