No, the key supplied during luksFormat is the initial skot-0 key. The masterkey is generated or can alternativly be supplied on the same command line. This is covered in the man page (as well as the FAQ AFAIK). Quote from man page: luksFormat <device> [<key file>] Initializes a LUKS partition and sets the initial passphrase (for key-slot 0), either via prompting or via <key file>.
