That section is titled Nationals and citizens of United States at birth

“The law” in this case does not have the authority to modify the intent of the constitution, which relies on the well known common usage at the time of its creation: Both parents must be citizens at the time of birth to be a “Natural Born” citizen as referenced in the constitution.
Statute law does not amend the constitution.
