While the overloading is annoying, database normalization actually has a strict definition that is not unlike the standard mathematical use; that is, to imply consistency (to make normal): https://en.wikipedia.org/wiki/Database_normalization
I would also point out that normalization within mathematics does not have a single concrete definition either, and it depends on your domain and desired property to stabilize: https://en.wikipedia.org/wiki/Normalization_(statistics)
Just to be clear -- I'm not annoyed really, I actually find these little momentary confusions to be a charming little quirk of our language. And I think it is not a big deal anyway, 99% of the time we're talking inside our fields where it is obvious what we mean.
