Chirality refers to the type of twist. While the side of the cord that is inner or outer will stay the same, but if you're looking from one end toward the other, the cord will approach you in a clockwise or counter clockwise circles. Possibly clearer, if you imagine screws[1] that are turned clockwise or counter clockwise to drive into a hole. A kink where the chirality is different on each side is different than a kink where it remains the same on each side. It is possible to create a disturbance where the chirality or twisitng remains the same on both side of the disturbance. Here is a drawing of how to create a disturbance in a telephone cord.[2] And, here is another drawing where two rigid rods have a flexible connector.[3] In these cases the chirality is the same on both sides, so you could just undo the loop. However, in the photograph that was posted, the chirality has changed[1]. So, you would have to straighten and recoil one of the sides to match the other's chirality.
