If I recall correctly, the photo you show is the way CHABAD wraps the tefillin on the hand. What you perceive as a Lamid is actually a Daled. CHABAD (and I'm sure many others as well), form the 3 letters of Hashem's name (Shin- Daled and then a Yud) on the arm/hand. The Shin is wrapped at the top, three twirls around the base of the tefllin shel yad, the Daled as per your picture and then the Yud is the ring around the finger.
They also spell the same SHAIM when wrapping the tefillin away in the boxes. On the shel yad box the strap is wrapped so that a Shin is formed on the bottom of the box (sorry, I don't have a picture to show). Also the wrapping on the Shel Rosh has a Daled formed on the bottom of the box. The Yud is the knot of the Shel Yad.
I would also like to add that I remember something about the letters of that SHAIM being elsewhere on the tefillin.
The Shin is the wrapping around the shel yad base. The Daled is the knot at the base of the neck on the shel rosh (different minhagim for how this knot is made), and the Yud is the knot of the Shel Yad. So many configurations. I would need to look in either the Rav Shulchan Aruch or find a Minhagai Chabad sefer to jolt my memory. Just thought this might help (or confuse even more), with this subject. A Freilichin Lichtige Chanukah.
