Doesn't matter what you believe he is trying to do.

The Ark case is clear precedent as to children born here of non citizen parents here legally. That part will never be reversed.

The legal ambiguity that needs to be addressed is whether Ark intended to grant citizenship to ALL children born here or just the ones whose parent or parents were here legally.

Ark read literally and restrictively directly applies only to children whose parents are in the country legally.

And the 14th Amendment contains the clause "and subject to the justification of" in addition to "born in the United States."

So the Court at a minimum had to clarify what "subject to the jurisdiction of" means because it is an additional requirement to being born here
