As would shooting up at an elephant's head. The bent knee looks like he may be starting to try to step to the side as the bull starts falling.
Don also isn't a big man, and the angle of muzzle looks like its around the top of the elephant's head. A 9.3x62 doesn't kick a vast amount, but it kicks enough to raise the muzzle some, exactly how much depending on the stock, load, etc.
