"Attack (Lock): Spend 1 charge . After this attack, you may perform this attack as a bonus attack against a different target at range 0-1 of the defender, ignoring the lock requirement."
The card simply says you may perform this attack as a bonus attack. Meaning you may perform this attack again, whereby you start the card text again; and spend 1 charge.
