It is exactly what I am describing. In any test you will have false positives. Then the broader you test the more false positives you get. This was also a thing during Corona in Germany. At the start of the pandemic only people with symptoms should get tested, because with low case number and even a very good test and test procedure you can easily get more false positives than true positives. This is true for every test where true positives are rare. The math is pretty simple here.
