Yes it does. This works on fake GTS like Pokecheck or PokeGTS. When using PokeGTS you can randomly just get Pokemon and when you look for a specific Pokemon on the site itself and press send to GTS the Pokemon will appear in your GTS like a Pokemon that has just been traded over. But this isn't recommended because with PokeGTS and rarely Pokecheck you get a lot of communication errors and it can take a while before they appear in your GTS so it is just better to trade with trainers.
