Six feet is not a lie, it is a guideline.  Of course it does not mean that is some sort of "cone of infection" within which COVID-19 will be transmitted and outside of which it will not.  Transmission is probabilistic, with the probability of transmission inversely proportional to distance between them (likely as a factor of the square of the distance), and directly proportional to the amount of viral shedding by the infected patient and the length of time of the interaction.  It is also related to the setting, air circulation, and (likely) temperature and humidity, and mask wearing.

As always, one can only reduce risk, you can't eliminate it entirely.  Shorter interactions with fewer people from further away will reduce risk.  There is no magic about 6 feet, but there is a good chance that the risk is falling rapidly around the 6 feet mark.
