In my distant past I used to be a military air traffic controller, also certified and managed civilian traffic. This seems crazy to me. In my world you would give pilots the simplest next instruction and ask them to report. Even with the simplest possible instructions, and mostly extremely good/experienced pilots, you have mistakes, can't imagine what something so complicated results in.

EDIT: though I guess this conversation isn't during the actual flight, it's some pre-flight "discussion"/instructions?

EDIT2: or you break it down to chunks, make sure every chunk is understood before you move to the next chunk, is another common technique.
