Note that Bondareko's original was entered as a direct mate challenge in #21. It's equally valid as an endgame study because it's the only way for white to win apart from a few move repetitions near the end which do not count as serious duals in a win-study.
The extra moves have the effect of completing 3 counter-clockwise revolutions of the checkmating queen around the black kings residence d5 though not exactly on the same squares!
