That is all I tell Students & that's all they need to know, anything more becomes a complicated head-spin which ain't required.
I'm not confused but I've seen many others who have been. Your advice is similar to the almost total lack of advice given to RAF helicopter pilots (such as I was back then) forty years ago.
If that's all you teach your students, one of them will possibly one day come badly unstuck. Problem is, once you have lost tail rotor control, how do you work out which is (or rather was), "power pedal".
