1-Star Historical Significance not a rejection, yet is sole reject reason?

In the Sept 2021 AMA, it was stated that " For the rating on Historical and Cultural Significance, it does not actually affect the final decision." However, a rejection reason often seen in rejection emails states "The nomination does not appear to be historically or culturally significant." Why is this listed as a rejection reason if the rating for this category does not effect the final decision of a wayspot?

My question here seems to be a duplicate of Tehstone's below, which already has more votes.
So I'll concede my question to his.
