What's the full paragraph of where that c. 2. is? I'm not finding it in 3−7−2. TAXI AND GROUND MOVEMENT OPERATIONS of the .65Z. Here's that again, highlighted by me.
3−7−2. TAXI AND GROUND MOVEMENT OPERATIONS
Issue the route for the aircraft/vehicle to follow on the movement area in concise and easy to understand terms. The taxi clearance/route must include the specific route to follow. When a taxi clearance to a runway is issued to an aircraft, confirm the aircraft has the correct runway assignment.
Yes, pilot read backs should include the runway assignment. But if they don't, it does not change the Controllers rule to 'confirm' it.
