A command does not itself require repetition. The next distinction is stronger: the bare imperative does not carry repeated, separate exercises of the act merely because the speaker intends them.
Consider this Hanafi example: a husband says to his wife, طَلِّقِي نَفْسَكِ — “Divorce yourself.” He is giving her the authority to pronounce divorce upon herself.
Under this wording, she has one exercise of that authority. After she exercises it once, the same command does not give her another separate exercise. The husband's intention to grant repeated exercises does not make this bare wording convey repetition.
This is an example of delegated authority1; the wording and its limits belong together.
1. Delegated authority: in this example, the husband authorizes his wife to pronounce divorce upon herself.
