Ah, Vref=Reference LANDING speed, V2=TAKEOFF safety speed.
The technical answer is V2 protects you to a 30 degree bank, Vref protects you to 40. Yes, Cessna in this case expects you to fly your CLIMBOUT at a lower speed that you would fly your APPROACH. Cessna would not expect you to maneuver as radically on takeoff as on landing.
