Subcategories are primarily used for organization purposes, to break down further their parent category. Typically their parent category would contain all articles in the subcategories. While I don't know exactly how articles are chosen when it come to categories (probably just equal weight), I do know they depend on the categories of the page.

I believe the issue here is the number of categories you use on article pages. Each of the "Read more" pages relates in some way to the others that the effect you are looking for is just lost in a spider's web.

I have a category that has many subcategories, but if you were to pick a page in their parent category each time you would see pages from the subcategory the page was in at the bottom of the article (their parent was associated to all articles in the sub too, kind of nullifying it, personally the best highlight for subcategories). Additionally, every article has fewer categories. The more categories, the potential for less relevant pages (in terms of an individual subcategory) displayed tends to increase.
