This quote is irrelevant to presidential eligibility. The same decision already acknowledged that the 14th amendment does NOT say who shall be natural-born citizens. The same decision limits the operation of the 14th amendment to the children of resident aliens who have permanent residence and domicil in the U.S. The same decision specifies Minor v. Happersett defined NBC as birth in the country to citizen parents.
The quote is relevant because it shows that the 14th & NBC ARE THE SAME citizenship.
But then, there is a reason why birthers lose every time they go to court. And here is the reason: They’re WRONG.
Natural born citizenship is the American phrasing of Natural Born Subject, as the WKA decision goes on to discuss at length. I realize you are incapable of understanding sentences, paragraphs, and, heaven forbid, pages. For those who are not, here is the WKA decision:

James Monroe, July 4, 1795.
A Mr Eldred was lately apprehended at Marseilles and sent here under guard upon a charge of having given intelligence to the British of some movement in the French fleet. Upon inquiry I found he had my passport granted too upon the most substantial documents proving him to be an American citizen; but I likewise found that in truth he was not an American citizen, for although born in America yet he was not there in the course of our revolution but in England, nor had he been there since. From what I hear of him, he is not a person of mischevious disposition nor one who would be apt to commit the offence charged upon him, but yet I do not see how I can officially interfere in his behalf, for when once a principle is departed from, it ceases to be a principle.
