The lifted stitch is worked adding a stitch to the right needle and then turned and worked on the wrong side.
It means a k2 p2 k2 becomes a k3 p2 k2 when one turn is made. After a few turns there are some k3 or p3 in each place where the turn was made. If I work back even as in the video (ie not trying to bind off but working every stitch through the back loop) there are several extra stitches so I no longer have k2 p2.
There is a different video for shadow wraps which I just found, by the same person and they are worked differently. No extra stitches, only the shadow stitch which she resolves on the final row working them together.
