Help with a pattern stitch

[krismorales]

I am planning on starting Sugar Maple socks by Melissa Morgan-Oakes. The pattern calls for a twisted stitch (?) or maybe a faux cable(?). I can't for the life of me figure out how to do it. The words are simple, but I can't think it through. The pattern says to "Knit 1 through back of loop of second stitch and leave on left-hand needle, knit into first stitch and move both stitches to right-hand needle."

I guess my question is when you knit into the back of the loop of the second stitch, you have a loop on the right-hand needle, but you leave the second stitch on the left-hand needle. Then you knit into the first stitch and move both to right-hand needle...won't that give you and increase? What am I missing. It's not supposed to be an increase.

I'm sure when I get the answer to this, it will be a slap in the head - "how stupid can I be" moment....but at this point I am clueless. All help will be apprectiated.
