I think it gives the answer but very briefly - "It clashed with expensive foreign spices". Essentially the Italian cuisine that formed wasn't really compatible with coriander.
I like coriander but my general sense is there aren't any Italian dishes I'd want to add it to whereas it's perfect with many Mexican, Indian and Chinese dishes I know of.
