That is not true. With a split phase system, like here in the US, you only need one if the legs of the 115 are on different phases
EDIT: This is the only requirement which no one seems to follow:

(B) Dwelling Units. In dwelling units, a multiwire branch
circuit supplying more than one device or equipment on the

simultaneously all ungrounded conductors at the panelboard
where the branch circuit originated.
