I am really sorry but I just cannot seem to understand what you are saying.

Are you saying:
1) start with good sensors in both banks with no codes,
2) see code P2626 in bank 1
3) swap sensors between bank 1 and bank 2
4) Bank 1 codes reappear after driving 150-350 miles but bank 2 remains good, no codes (what I put in the imaginary timetime)

or

4) Bank 1 code appears after driving 150-350 miles but bank 2 codes quickly, indicating the sensor originally in Bank 1 was permanently disabled (NOT what I put in the imaginary timeline).

I'm sorry to be so insistent on this but I think the details might be important. Could you start with my imaginary timeline, read it carefully, edit it so that it reflects reality as much as possible and post it?
Step 4 of that would be bank one and 2 codes both appear, indicating that the oxygen sensor is being killed each time.
