i don't fly the 330 so i don't have a clue, but as an 320 driver I say thats too long, maybe compare to the auto land?
FCOM 320:
At Touchdown:
Derotation ... initiate
-lower the nose wheel without undue delay
-The PM continues to monitor the attitude
ALL THRUST LEVERS .................... REV MAX or REV IDLE
The flight crew must select reverse thrust immediately after main landing gear touchdown.
