It depends how the air / ground logic system on the A330 works. On the 757 / 767 only the main wheels need to have made contact for the aircraft to decide it is on the ground, and for features such as auto-spoilers / autobrakes to become active. Reverse thrust can of course also be used once this is the case.
It is possible to use an aerodynamic braking method (with spoilers / full reverse) holding the nose wheel off the ground completely to assist with deceleration. The nose is of course gently lowered before the elevators lose their aerodynamic control authority.
Anyway I digress... on the 757/767 the air/ground logic system simply requires both main landing gear tilt sensors to detect ground contact, and both thrust levers to be at idle to sense "touchdown".
I used to love the smell of Jet-A in the morning...
