The line of ancestors isn't the only set of Y-chromosomes that would
be erroneously assigned to the clade. Any men that are G generations
away along Y-chromosome lines would be erroneously assigned, e.g., the
founder's brothers and their sons, his paternal uncles and a whole
bunch of other men who aren't his descendants but are linked via
patrilineal transmissions with no more than G steps.

As long as a Y-STR haplotype-based test is used to define a clade,
then this test will be passed not only by the patrilineal descendants
of a single man, but also by many other men who are not.
