You'll strangle yourself with all that red tape!
The legal sense of the term 'instruction in flying' is toward the completion of a rating or licence. It is not a general term and doesn't mean the same as it would outside of the legal document.
What you're saying is that a pilot who perhaps wants to learn and investigate accelerated autorotations may NOT ask a more experienced pilot (not holding CRI) to accompany him for the purpose of demonstrating or for safety's sake.
So, to stay legal, he goes off on his own.
Doesn't sound like the law serving safety to me.
