Bruh, this is not semantics; it is the described mechanics of the Magical God's powers. The Magical God never destroys, he only creates. Othinus is not a goddess who destroys, but a goddess who creates, even if the world she creates is a destroyed world. Even the act of destroying all the walls of the Phases is still the act of creating a new Phase.
Being nonhuman does not mean to be higher than a human in the hierarchy. The fact that you exist in the same world as a human is enough for your soul rank to be human (even an angel or demon lowers his soul rank when he enters the human world). And a human is a human, as Coronzon said, a human always remains a human, regardless of his position in the Sephiroth Tree of the human world. Even the Magical God who is at position 8=3 in the Golden Dawn system is still human from a global perspective, so he is bound to the surface of the Four Worlds. You can't increase your soul rank without the help of a transcendent being like Coronzon or Qlipha 545.
This is because the Coronzon weakened even more than the Magical Gods. The Magical Gods became weaker, but they still remained within the boundaries of their world, meaning that the weakening occurred within the boundaries of the human world. Unlike Coronzon, who had to lower her soul rank to the human level and then create a flesh-and-blood cage for herself, which made her unable to use her magic normally (she herself said that using a human body was a pain). And even with all that, the magic gods could not harm Coronzon, only his avatar, whom she was able to heal in peace. Even Aleister Crowley admits that it is impossible to defeat Coronzon, though he has enough knowledge to kill the Magic Gods.
