if条件句 的一种不符合曼哈顿上介绍的形式~

stellalights

In many nations, criminal law does not apply to corporations, but in the United States today, a corporation commits a crime whenever one of its employees commits a crime, if the employee acted within the scope of his or her authority and if the corporation benefited as a result.

这句句子里面 if 过去式，(then)现在式，不在曼哈顿介绍的5中 if then的结构中诶~~
if A happens, B happens.
if A happens, B can happen
if A happens, B will happen.  (if A has happened, B will happen)
if A happened, B would happen.
if A had happened, B would have happened.

曼哈顿上说出现的if then结构一定会落在这5种形式里，那这句算什么呢~~？

我只能说，如果这样的套公式，那就成了XDF。
