Well, they’d have to, to be fair. Roe v. Wade gave women a federal right to have an abortion, in any state. When they struck Roe v. Waid down, the right to have an abortion just fell back to the states. In your example, if, say, New York argued Roe v. Wade still existed, would they be arguing that it existed in Texas? New Yorkers still have the right to abortion, but no state court in New York would be allowed to rule that Texas citizens also have that right.
