This isn't surprising. The fastest way to get dangerous foreign materials in the lungs out of them is obviously to exhale them.
If proven this would mesh nicely with my own anecdotal experiences. I've been treating my own respiratory illnesses at home for the better part of a decade under this assumption, and that includes three moderate cases of COVID-19 so far. Even if it's cold I spend as much time as I can outside in the open air. I usually recover in about half the time I would if I stayed indoors.
