The ACs, if properly installed and functioning, do not mix outside and inside air, so they're no more concern than the "openings" in the roof for e.g. the fridge or the TV antenna.
More generally, the space is less confined above the RV than below it so the exhaust gasses tend to disperse more rapidly and over a greater space. Also, they're warmer than the surrounding air in general, and have an upwards draft through the gen-turi, both of which tend to help them ascend rather than spread around.
It's certainly not impossible for them to get into the motorhome through a roof vent if the conditions are right (wrong?), particularly if you have a fantastic fan or similar device set to pull outside air in. In practice, it's apparently not a very common difficulty. (It likely also helps that many people run the generators primarily to power the air conditioners anyhow, and presumably when doing so don't leave the roof vents open to any great extent.)
