Comment(by prettyboymp):

 Only if its a tag, category, author, or other queried object.  While that
 covers most of the situations, it doesn't cover all of them, which is why
 the filter is needed.

 The specific instance I needed this was while using a custom post_type of
 calendar_event where the events for a month were displayed with a
 permalink structure of /events/year/month/.  I didn't want a month
 returning a 404 just because their weren't any events scheduled for the
 month yet. My only work around was to falsely set is_category as true on
 'posts_selection' then remove it on 'template_redirect'.
