因为他想说: 当过去的某个动作A发生时,另外的某个动作B就已经完成.是在表述一个发生在过去的事情,所以A相对于B来说,就需要用过去完成时.如:Hardly did he come back, when I had told you about it.
他一回来,我就告诉你了呀.

这个时间状语从句，后面主句你没写出来我猜主句应该是过去时，从句用过去完成时表示从句谓语发生在主句谓语之前，所以这里不直接用He stepped

这是时间状语从句后面一定还有半句而这半句发生的动作发生在过去那踏进饭店大门的动作就是过去的过去所以用过去完成时e.g. When he had just stepped into a restaurant door, Tom saw his girlfriend immediately.

When he had just stepped into a restaurant door,这里有表强调的意思.就当他那时刚刚踏进餐馆门的时候,.......发生了.
