Is a person's intent not used up when it is used to convict them of murder?

^5. "[A] person's intent to kill the intended target is not 'used up' once it is employed to convict the person of murdering [the intended] target. It can also be used to convict of the murder of others the person also killed." (People v. Bland (2002) 28 Cal.4th 313, 322.) "[A]ssuming legal causation, a person maliciously intending to kill is guilty of the murder of all persons actually killed. If the intent is premeditated, the murder or murders are first degree." (Id. at pp. 323-324.)
