The categories appear due to the example. (Edit: because the "example" is a live use of the template, and therefore includes the category.)

Splitsection doesn't add a category, Inuse uses a category parameter, which is set to nothing on the doc subpage.

I haven't see the category parameter solution before, but it's definitely one solution.

Personally, I usually have a namespace check, although a pagename check would work just as well.

But personally, I also stopped using /doc subpages a while back - I believe the reason for them is so that the template can be protected while the documentation is freely editable, but your templates aren't protected anyway, so you don't need to use /doc subpages. They make sense on huge wikis, but aren't really necessary on smaller ones.
