You are right, I am not an expert. It would be nice if there was an expert here. I would not consider a salesman at oxygensensors any kind of expert, either. The one thing I know for sure is that designing a sensor to use the exhaust as a ground source is the height of stupidity. In this case you have mechanical junctions subjected to high heat. This will cause oxidation of the metal, and you will lose the electrical connection. This is an eventual inevitability, not a possibility.
You make some statements that contradict each other. You say that a few hundred ohms may not create a sensor fault, while at the same time you are suggesting that cleaning the ground will remove a sensor fault. Which is it? You have also previously suggested that a few ohms will cause such a fault.
You do make a good point that if there are faults on both sensors, then it is likely there is a common problem such as a bad ground. Does it not work in the reverse, that if only one sensor shows a fault that it is UNlikely there is a ground problem?
Time has a value as well as money. I could have spent several hours or more taking apart the exhaust to try to provide a good ground to the cat pipe, and it would have been for nothing.
This issue will likely not be settled without some serious research and debate.
