Oh, I thought the transactions were already broadcasted, just weren't being confirmed?
edit: not on a blockchain means not confirmed. A transaction that's been broadcast but not confirmed yet is probably still in the transaction pool of some miners - as soon as it becomes valid, it might get confirmed even without the original sender rebroadcasting.
