It was not clear, and in fact the courts ruled the other way in Texas v. White. Further, any reservations that were mentioned at the time of ratification were not duplicated when the states were re-admitted after the Great Rebellion. So any reservations by the states during ratification are no longer in effect.
New York was re-admitted? (Patrick Henry guided NY ratification as well as VA.)
Please, from a legal matter the issue is far from settled. At the time of ratification of the Constitution the original intent clearly included the States right to withdraw, under certain conditions.
