Interesting. Would you mind explaining the logic? Never heard of this before. Never been on an A330 btw.

I would guess it is a DSG (design service goal) limitation (cycles).

Check Airman: it was a mod. introduced early on in the A330 career, mid. 90s if I remember correctly. The aim being to reduce fatigue life on the airframe. It came in with the increased gross weight versions which started to do much longer ie. 8hrs + sectors.
They also introduced a modified fuel trim tank loading schedule based on sector time as well.
And, did I mention variable ZFWs and variable MTOWs?

Isn't that good for passengers as well? (having just taken a 14 hr flight on an A330)
