Do I read this article correctly? In a residence, a common disconnect is not required if the circuits do not terminate on the same device or yoke. IOW, I can run 12/3 from two adjacent breakers in the panelboard to a j-box, then split off into two separate 12/2 runs for small appliance circuits? I bet alot of elec's use common trip breakers anyway. Don
Your interpretation is correct except it can also apply to "other" than Dwelling Units, see 210.7(C). The key here is, if we are using a "Multi-Wire circuit it is only one circuit.
Also the breakers do not have to be ajacent to one another, they only have to be on different legs or phases.
