when it came out〜 の come out は「〜が明らかになる」という意味で、it は形式主語です。that節が意味上の主語なのですが、came out の直後の that they had both been looking forward〜だけを意味上の主語とすると、全体の意味がとれなくなります。この文章では、that節が３つ続いているのです。
that they had both been looking forward〜
when it came out＜ that it should have been made〜
that they should have met there〜
★should は「驚きなどの感情」を表しています。
