The connection changes its form, not its purpose
In closed position, there are several points of contact: your joined hands and the embrace around the back, with the corresponding contact at the arm or shoulder. When you open up, some of that contact disappears. The remaining hand connection therefore does not suddenly take on the task of holding the other person in place. It still communicates where your shared movement is going.
For a simple transition to an open facing position, the distance between you increases as you step. The hand at the back is released before it limits the distance. At the same time, your joined hand follows the changing distance. A soft elbow makes room without letting the information disappear completely. Soft means flexible, not hanging limply.
Even in open position, you are initially still oriented toward each other. A side opening, where you change your orientation, is a different spatial movement. The guide to Cha cha cha Hand to Hand explains how this becomes a specific figure. Hand contact alone does not reveal which figure you are dancing: body orientation, direction of movement, and timing give it meaning.
