I was thinking along the same lines. Even O'Connor didn't uphold Roe, when O'Connor composed Planned Parenthood, point being that "upholding" can be a more complex discussion when applied to some issues (it is with abortion), and a simple discussion and application for others, like "one man one vote," and "separate but equal."
No matter - the pattern of how and what to answer is pretty well developed over the course of the last half a dozen nominations.
DiFi asked if there would be another round. Specter indicates that he hopes not, but the matter is still undecided.
