I haven't tried it myself but apparently after trading away the Pokémon you want to clone, either over local wireless or Wi-Fi if you turn off your 3DS about 4.5 seconds after the "Communicating. Please stand by…" message appears you will keep that Pokémon on your 3DS and the other player will receive it too, but you won't receive the other Pokémon and it will disappear on the original owner's 3DS.
Example: Say you trade a Mewtwo holding a Master Ball (player 1) for a Pidgey (player 2). You wait until the trade animation finishes and then the game says "Communicating. Please stand by…" on both games. You then turn the power off on player 1's 3DS about 4.5 seconds after the message appears. Apparently, you'll then get a blank screen on player 2's 3DS and if you didn't it probably didn't work properly. After restarting the game on player 1's 3DS you'll still have your Mewtwo holding a Master Ball but player 2 will have a Mewtwo holding a Master Ball too, but the Pidgey will disappear and not appear on both 3DSes.
I think this is how it works. Again, I haven't tested this myself. If I made an error, let me know.
