I have a template with conditional inclusion in categories, something like this:

 {{#ifeq: {{{var}}}|A|[[Category: A]]|}}
 {{#ifeq: {{{var}}}|B|[[Category: B]]|}}

When opening page with such template used, correct category is shown. But when you go to category page for any of these categories, all pages using this template are listed there. 

It looks like queue process, which adds links to categories, doesn't run ParserFunctions, but simply looks at code, ignoring any conditions.
