If I imagine the larger coaxial gear being held still while the planets walk around it, the torques exerted by both motors are equal (as I've added a gear ratio upstream) in order to keep the center gear still. It also seems like the module rotation speed is one-half the rotation speed of the larger planet gear, so there's definitely some kind of a virtual gear ratio acting here.
That doesn't mean that I know the overall output torque of the module, however. Given that differentials are usually "torque in = torque out" devices, you're probably correct now that I think about it.

And with that I mournfully cancel my plans to make at least part of this module this weekend.

That being said, this GIF might just be the gold standard for displaying a complex assembly. If anyone wasn't clear on the gearbox after your sweet color coded cross section (which was also incredibly useful), I think they are now.
