Well there you go, something stupid in the ANO.
I'm pretty sure all of the Flying Examiners I've met didn't even know that was a requirement.
That said, what I mentioned already stands, it's sensible to take an instructional flight on a new aircraft type which would account for "appropriate differences training". Just make sure you get your logbook signed
/stickered.
It's still completely wrong even if it is in the ANO.
