Clazzio Seat cover install help.

[A1phazu1u]

So I'm installing my leather seat covers for my sedan and I have a question about installing the back seat covers. when the seats fold down there is a lining on the back of the seat that matches your trunk lining. Am I supposed to remove this, install the leather seat cover, then replace this lining on top of the back of the leather seat covers? Doing so would mean I'd have to pierce holes in the back of the seat cover to accomplish this. Thanks in Advance.
