No, it's not at all deceitful. The quotations emphasize the mindset of two of the most conservative Justices on the SCOTUS in reference to citizenship issues. As a matter of fact, someone (and I don't have time or inclination to find it), referenced Nguyen & Boulais v. INS as supportive of the NBC argument, here on FR, very recently.
Deceitful is in the eye of the beholder.
