求助CFA L2 book1 page 516 forward position against, selling, forward, months, position

shell_study

书上这样写的：
Laurier Bay Capital had a long forward exposure to the USD, which it hedged by selling USD 10 million forward against the NZD at an all-in forward rate of 0.7900 (USD/NZD). Three months prior to settlement date, it wants to close out this short USD forward position.

看了答案糊涂了。
我的理解是先买进usd，settlement day卖出usd，但看答案好像不是。究竟这过程是怎样的？

先谢过大家的解答。

题目的背景是，LBC本来有USD的多方敞口，为此它卖出了美元forward。为了close out这个forward，它当然要在合约到期前3个月买进USD了。
