When I started skating older guys told me you can’t switch your stance mid air, if you pop nollie you just can’t land on any switch position it’s always gonna be regular something unless you turn 180 when it’s fakie. I know there’s few exceptions, like fs 180 to ss crooks and so on but I was thinking those simply came from to ease up things while chatting with mates. I think that’s nollie 270 to noseslide too.
