isn't the carbonyl oxygen more nucleophilic ?

I mean shouldn't the carbonyl oxygen attack AlCl3 ?

This is a common mechanism. Many questions had come from this reaction, so I don't know the proper reason.

Both of these oxygen will attack , but when cabonyl oxygen attacks then no proper product will be formed and hence reaction will stop , and on the other hand when the conjugated O attacks a product is formed and hence reaction shifts in forward direction and this reaction only yields the final product
