Not another ship, any ship at range 1. Your initial Jam removes the first token which causes the Jam token to be spent, then the two copies of ISB Slicer trigger at the same time so you can choose the order. You re-Jam the same ship since it no longer has a Jam token, which spends that Jam and removes the second token. Then the third Jam kicks in.
