I presume all or most of us know that it is to be understood as an additional A330, not a new one in the sense of "brand new from the plant in Toulouse". It's new in the sense that it is a new addition to the fleet, but it's a pre-owned aircraft. You must have know that, Boeing767copilot, mustn't you ?
And if SN announced on Twitter the arrival of a new A330, if they used these words (I didn't check), it shows again they are not good at using words correctly and at formulating their communications properly without creating ambiguity. But communication is not b.air's strong point.
