For example, if Player 1 moves UP-'''and'''-RIGHT then UP and RIGHT are shortcut with each other. In result, without the diodes, Player 2 would automatically move UP-'''and'''-RIGHT whenever trying to move UP-'''or'''-RIGHT.
'''Caution:''' The CPC+ has some kind of built-in Y-cable with only 8 diodes. But, for properly supporting the included 2-button joypads it would require 12 diodes.
