Zone 1-A is for direct round trips on the international portion (like NRT-ORD-NRT) on partner airlines, and the pricing is the same as for Regular Season ANA flights. You can still have domestic legs within Japan.
(The key point is "only two international legs", so open jaws probably are't ruled out.)
Zone 1-B is for less direct trips on partner airlines originating or ending in Japan.
