I think what laypeople and experts mean by "asymptomatic" is different and contributes to talking past each other. One of the first symptoms of this coronavirus is a dry cough. These people would not be considered asymptomatic in the technical sense because clearly they have a symptom. However a cough is such a common thing that healthy people do all the time, in a practical sense a person who only has a cough is functionally asymptomatic and able to go about their daily lives. It is only when they develop a fever that they become sick enough to notice.
