这句话里的as起什么作用

My husband is freelance : he works for several different companies as and when they need work done – he’s a computer programmer.

这句话里的as起什么作用？感觉是多余的。

牛津字典的解释：

as and when

（用于在特定条件下才会发生的事情）将来…时，到时候
used to say that sth may happen at some time in the future, but only when sth else has happened

We'll decide on the team as and when we qualify.

将来我们具备了条件时就会决定成立这个队。

I'll tell you more as and when (= as soon as I can) .

我一有可能就会告诉你更多情况。
