I see, but it was a legitimate trade. I checked out the pkmn I sent over to my Pearl game. They were legitimately found and caught in game, and simply used as place-holders to trade my dratini and porygon over to my Platinum. Both of those also said they were "Apparently met at Lv. 2".
So, if it is a legitimate trade, between games, it will always say "apparently". After all, I will never have the exact same ID and SID with two game chips.
