Yes, ANY page/template transcluded on the page you're protecting, will be protected as well, if cascade is selected. It doesn't have anything to do with folders, or who created them, according to that help page that I linked to above (I've never actually used it myself).

To clarify, the page you were intending to protect was just your profile, not a category. If you were to cascade-protect a category, this would only apply to links in the category description (if any), and not any listed contents/subcategories.
