Here's the conclusion from the study that was linked: "Droplet transmission can occur at a distance greater than 2 m if there is direct air flow from an infected person. Therefore, updated guidelines involving prevention, contact tracing, and quarantine for COVID-19 are required for control of this highly contagious disease."
Walking by someone is an interaction measured in seconds. If that person is infected and shedding via aerosol then a plain cloth mask does not offer much protection. The cloth mask would offer some level of protection if the infected was shedding via droplets from sneeze/cough/etc.
If there's direct evidence that wearing a mask on my walk around the neighborhood offers significant benefits then I will reconsider. To this point, I just haven't seen anything that supports this behavior.
