Same reason why ghosts on Ms. Pacman on the 8-bit Atari computer flicker[0] when they overlap horizontally. The flicker is slower so looks more like flashing rather than flickering. The Atari has 4x 8-pixel wide 'player' overlay graphics that were single color has a horizontal (but no vertical) position, and spans the entire vertical height (so 1 byte of data per scanline), as well as 4x 2-bit wide 'missiles' which could also used as a 5th player. In the case of Ms. Pacman the missiles are used for the whites of the ghosts' eyes. [0] https://youtu.be/p43aO7JhmN8?t=94 https://youtu.be/p43aO7JhmN8?t=94
