Why do we need organization name here, in tests?

to prevent the test from creating directory ~/.config/Unknown\ Organization/, which looks a bit unorderly.

I mean, it is not clear how does this work and why only one test needs this line.

Without a comment, this line will be discarded in the future as redundant and irrelevant to the context.
