As pointed out by Nanaki, you linked to Semantic MediaWiki (SMW) documentation. That is an old extension that is no longer available to wikis. Even if it was available, it wouldn't impact the category pages. What it is referring to is how the selection criteria are interpreted for its parser function "#ask". What it is saying is that if you use "Characters" as your selection criteria, #ask will return pages including those that are in "Characters from Beetleburg".

I am not certain about how it is "supposed" to work, but, as someone who has used subcategories for a long time, I can tell you that pages in subcategories do not show up in the list for the supercategory. Similarly, they do not count towards getting badges (if you have Achievements enabled). What I don't know is how DPL will treat them. If DPL treats them the same way as SMW, then you can use DPL to create the page list; although it would be above the subcategory list rather than below it. I would guess that DPL would treat them the same as SMW because it is supposed to be SMW's replacement.
