(b)    A donor’s revocation of an anatomical gift of the donor’s body or part under § 4–504 of this subtitle is not a refusal and does not bar another person specified in § 4–501 or § 4–507 of this subtitle from making an anatomical gift of the donor’s body or part under § 4–503 or § 4–508 of this subtitle.

(c)    If a person other than a donor makes an unrevoked anatomical gift of the donor’s body or part under § 4–503 of this subtitle, or an amendment to an anatomical gift of the donor’s body or part under § 4–504 of this subtitle, another person may not make, amend, or revoke the gift of the donor’s body or part under § 4–508 of this subtitle.

(e)    In the absence of an express, contrary indication by the donor or other person authorized to make an anatomical gift under § 4–503 of this subtitle, an anatomical gift of a part is not a refusal to give another part or a limitation on the making of an anatomical gift of another part at a later time by the donor or another person.

(f)    In the absence of an express, contrary indication by the donor or other person authorized to make an anatomical gift under § 4–503 of this subtitle, an anatomical gift of a part for one or more of the purposes set forth in § 4–503 of this subtitle is not a limitation on the making of an anatomical gift of the part for any other purpose by the donor or other person under § 4–503 or § 4–508 of this subtitle.
