746.2.a. Choices made for the additional execution do not have to be the same as the choices made for the initial execution. Example: Rocket Barrage is a spell with [Repeat] [4][C] and “Choose one — Deal 4 to a unit in a base. [or] Kill a gear.” If Rocket Barrage’s controller pays its Repeat cost as they play it, they may choose the same mode or a different one, and if they choose the same mode, may choose the same target or a different one. If they choose “Kill a gear” twice and choose two different gear, they must specify which gear is the first target and which is the second. As the spell resolves, those two gear will be killed in the chosen order.
