I'm not sure about the text, I wasn't looking at the game when I wrote the post, but I am quite sure that there is some sort of error here: The NE has required Temples in all/75% cities in VEM for a very long time, so unless Thal changed his mind, decided to change the way the NE requirements work compared to other NWs (no other NW requires a different building in the city) and didnt document it - none of which seem likely to me - there's a mistake.
