He’s saying if someone gets in the habit of using that style they have to be very careful. If they forget to change True to False when using an OR that it could have major consequences. Performance being the least of concerns.
I agree that such an error would be of the catastrophic type. It's interesting that several people seem to perceive this formatting approach as something that would increase the risk of that error. Is the red flag for people the WHERE TRUE on one line? Like, would this be less alarming to people?
