I am not 100% sure that i understand your question, but what is shown in the search results are not only determined by the URL.
If the title on the two pages are different, it will be quite unlikely that they will show up together...
Point beeing - even though you have the same wording in the URL, it will not mean that the two pages will show up together in search results...
My answer is off course based on the assumption that you are talking about external search engines and not your own internal search on the site
