I am not sure what the author of this is trying to get at.

Of course markers mutate over time. That is how we determine how closely related the descendants of a common ancestor are, by how closely their markers match.

As to false matches due to unrelated Y chromosome DNA mutating to match over the generations, that is called convergence. It is extremely rare.
