What is the ruling regarding a piece of skin where the top connection is in one obligatory area, the bottom connection is in another, and the middle section is detached ('hanging loosely')?

Primary text

If the skin is connected at one of the two required locations and the middle part is detached and hanging, it is treated as if it is growing from both required areas. It is obligatory to wash the portion of its exterior and interior that aligns with the obligatory area, and to wash the area underneath it that belongs to the obligatory washing zone.
