That's classic SOP for inadvertent CB entry and is standard kit for an airline pilot. Perhaps it wasn't discussed because of this, but it's good to see it said. They're essentially the same items as handling an unreliable airspeed indication except a couple of pitch-power memorized items to stabilize the aircraft for troubleshooting.
As has been pointed out here many, many times now - doing both, (failure of all flight data and possibly attitude information while inside a CB), would have a very low possibility of a successful outcome, in any aircraft.
