He was also the leader the team needed, motivating them when he needed to, fighting for them when he should, and leading by example every single time.

他也是团队需要的领导者，在需要的时候激励他们，在应该为他们而战的时候为他们而战，每次都以身作则。

So the meaning here is very similar but it's not exactly the same because with until, the focus is on the period of time leading up to the endpoint.

这里的意思非常相似，但并不完全相同，因为 until 强调的是指向终点的一段时间。
