Your theory is entirely possible. But I’d also like to point out that the study population was entirely Covid positive people with one or more risk factors. Presumably if you’re overweight, over 60, and have Covid you probably are willing to take more risks than before to improve your odds of not dying. Even the vaccine hesitant might accept that risk.
