If I understand correctly, I believe what your referring to is allowed by 210.4[B] and 210.4[C], exception No. 2. The disconnecting means in this instance doesn’t necessarily have to be a common trip. The 2008 Handbook exhibits 210.1 and 210.2 on page 76 and 77 gives an excellent depiction of this. Hopefully this is on target with what you were asking.
