Not necessarily. DOMA prevented their marriages from being recognized by the government, so they were never able to receive the federal benefits associated with heterosexual marriages regardless of whether they were married legally in a state that allowed gay marriage. It also prevent their legit marriages from being recognized in states wherein gay marriage was not legal, so you could be married in New York, but move to Ohio and be not married in the eyes of the law.
This was obviously unconstitutional and a serious problem. Now, if you are married in a state that allows gay marriage and you move elsewhere, your marriage is recognized by the Fed, and states wherein gay marriage is not allowed still must recognize your marital status.
You can see where this is going. It makes the states' decisions to not allow gay marriage arbitrary. It'll only be a few years before most states jump on the marriage bandwagon now.
