The legend rule exists to stop you from keeping two copies of a named permanent in play at once, and this card's whole premise is switching that rule off for permanents you control. What reads as a durdly rules-hack turns aggressive the moment the third clause engages: every nontoken creature that shares a name with another creature you control grows for each match, so a board of identically named bodies scales quadratically rather than linearly. Two of a name is a modest bump; four of a name is a stat line that closes games. The design pairs two effects that had rarely met before: permission to hold multiple copies of a legend, and an anthem that specifically rewards duplicating nontoken creatures. That nontoken exclusion draws the sharp line: the same-name bonus is only ever received by nontoken creatures, so tokens can never grow from it. But tokens still count for the creatures that do qualify. A token copy of one of your nontoken creatures contributes to the name-matching tally, feeding the scaling on your nontoken originals even while collecting nothing itself; a legendary token still picks up the flat +1/+1 the second clause hands to every legendary creature you control. All three abilities are static, working the instant the board state fits, which is what makes the payoff feel less like a combo and more like a permission slip.
