For me, this goes to the "principle of least astonishment".
The titles of many episodes are common phrases. It is not unlikely that someone might link to that phrase. It is a good thing that the default target for such a link is **not** a TV episode which happens to use it.
But in those cases wouldn't it be more appropriate to actually have an article about the common phrase? That way the normal disambiguation state kicks in and a parenthetical is warranted. Other episodes with titles that aren't common phrases wouldn't be disambiguated, but they also wouldn't be astonishing so they wouldn't need a special rule like this.
