"Like carbon dioxide, nitrogen dioxide is heavier than air so the highest concentration of gas is typically located at the silage surface, which is the area where a person will be going if they need to enter the silo for any reason." Out in the open atmosphere, there is enough motion in the air to keep the oxygen and carbon dioxide mixed up.

The lighter gas helium, now underneath, will ascend; the heavier CO2 will descend, and being a two-way countercurrent system there will be faster mixing than if it were by diffusion alone. A series of inversion, re-righting, re-inversion etc should result in a homogeneous distribution of gases between the two balloons.
