I have far more experience on the A330 than Mr.Allan, who was a newbie on the type.
So what if CA was new to the Airbus? He is a very experienced checker and I suspect his concerns relate to standards in general rather than anything specific to the Airbus.
It seems fairly clear that something is amiss at HKA. To add fuel to the fire, I've lost track of the number of times I've heard HKA aircraft (amongst others) ask for an early left turn off 25L at HKG due wx, whilst well below MSA. Have some of your people not looked out the window on a clear day and seen the big hills??
