If you bring the yarn to the back how do you knit it??
You usually knit with the yarn at the back, that is on the side facing away from you. Perhaps the videos on the Free Videos tab at the top of the page (see Knit) will better answer your question.
I'm wondering if they had you do something with the yarn in front on the last stitch (or step) and now they are telling you to put the yarn in the back and resume knitting in the normal way? Does that apply?
