Alito was asked about his personal experiences. Told explicitly that they wanted to know what was in his heart. Much like Sotomayor was asked to speak about diversity.
The difference is he never alluded to any notions that his job was anything other than what it actually is, applying the law. He made a point of going out of his way to say that even though a case about a child might make him think about his child he can not bend the law, favor an outcome, change the law, etc. As a judge he will apply the law.
He also never said having a penis or being Italian was gonna make him a better judge than some colored chick with a vag. Had he said that he wouldn't have gotten confirmed. All hell would've broke loose.
