Actually, your intuition could be right. From an academic point of view, It's hard to be certain if that story was true.
While all the Pali Patimokkha rules are also in the Chinese Pratimoksha (pretty much word for word), their supposed origin stories differ. This lead scholars to believe that the stories are later additions. Having read much of the Pali's Suttavibhanga (where you find the stories, rules and word analysis), I can't help noticing the distinct lack of correspondence between some of the rules and the attached stories. So, when I heard from a scholar monk about the difference of origin stories, I thought, "No wonder."
This is why I prefer to pay more attention to the wording of the rules themselves, rather than the story or the word analysis(which in rare occasions are at odds with the rule itself).
