In Pokemon XY, I want one of my Pokemon to have its hidden ability. If I put it up on the GTS, and have my friend trade me for it, then trade it back to me, will it gain its hidden ability?

Bulbapedia says: "Where possible, all Pokémon obtained from the Pokémon Global Link, either via the Pokémon Dream World or a Global Link promotion, will always have their Hidden Ability."

Does this apply to gen VI?
