I remember this subject discussed a few weeks ago but don't remember the answer.
I have 1- 12/3 coming from the attic into the top of a 4" square plastic outlet box. I want to power-up 1 duplex outlet with the "red wire" circuit and the other duplex outlet with the "black wire" circuit with common nuetral and ground. Then I want to come out of the bottom of the box with the 2 circuits and service additional devices.

This is actually existing from a previous Washer/Gas Dryer set-up, washer on one circuit, dryer on the other.

Is this OK by the code?

Yes this is probably OK. At the panel, these two circuits should go to different breakers. The panel has 2 hot buses.
The breakers should be on atop the other, one snapped into hot bus 1 and the other into hot bus 2. The handles of these breakers should then be connected (by a clip or a bar made for the purpose) so that when one trips, they both trip. This is so the next guy who goes into the j-box doesn't turn off one breaker and think there's no power there.

Remember, there will be 220V when measuring between the black and the red. The black/white will have 120V and the red/white will have 120V

Handle ties are only required when the two circuits feed receptacles on the same yoke. 210-4(b)
