The two classes were not referring to two classes of citizens, but to two groups of people, the one consisting of those who were undoubtedly citizens who were born to parents both of whom were citizens, and the other those who may or may not be citizens who were born to aliens or foreigners in the United States.

How do you figure a group of persons for whom you can't say to whom they were born is a class of persons??? This makes no sense. The two classes Waite was referring to was 1) Constitutional natural born citizens and 2) "citizens" as recognized by "some authorities" with no regard to the citizenship of the parents. There is doubt about the second class of citizens, but not the first.

2) "citizens" as recognized by "some authorities" with no regard to the citizenship of the parents.

Good. Now take the last step: "with no regard to the citizenship of the parents" is inclusive of those born of citizen parents. Thus, the "second class" is an expansion of (or, as Waite says, "going further" than) the first, not distinct and separate from it.
