The confusion is the term asymptomatic vs presymptomatic. Approx 20% of patients are truly asymptomatic... and they appear less likely to infect others. The amount of the virus they have tends to be lower so that’s why longer exposure to them (at home) would be more likely to be where the spread it vs out in public. That doesn’t mean the risk increases because people stayed home.
Studies have shown people are most contagious when they are presymptomatic right before they start displaying symptoms.

This study estimates 40-60% of cases was from people who were presymptomatic.

Not trying to be combative here. The doctor should have been clearer in what she was saying. She was not saying people without symptoms don’t spread the virus. She was saying people who never get symptoms are less likely to spread the virus.
