The previous computation was very different depending on the device's screen and accessibility options. Given that the keyboard is supposed to fill all the space in one dimension, the dpi unit makes little sense. The formula doesn't mean anything in particular, it takes into account both dimensions (x and y) and should be close to the dpi in the diagonals (which is the direction of swipe). This changes the actual value, on a 1920x1080 480dpi screen, the value is increased by 20%.
