This is a name given to the last part of the Hari-vamsa; Mesquita (pp. 62, fn. 103) adduces no reasons whatsoever for saying that it has ``nothing to do'' with that text. (The mere assertion that a quote is not found there is not sufficient--see section 3.) Names at a second level (names for parts of texts) such as Moksadharma are used by Madhva. The name can also refer to the last Parva of the Mahabharata itself--see the opening remarks of Raghavendra32(p. 1) in his Gita-Vivrti, where he names the eighteen Parvas of the Mbh., using this name for the last.
