Forum:Maiden with eyes of blue Effect question

So maiden with eyes of blue has the following effect: "When this card is targeted for an attack: You can negate the attack, and if you do, change the battle position of this card, then you can Special Summon 1 "Blue-Eyes White Dragon" from your hand, Deck, or Graveyard. During either player's turn, when a card or effect is activated that targets this face-up card: You can Special Summon 1 "Blue-Eyes White Dragon" from your hand, Deck, or Graveyard. You can only use 1 "Maiden with Eyes of Blue" effect per turn, and only once that turn."

It's the and only once that turn part that is confusing me. Is that just saying that each maiden is only good for summoning one blue eyes, or is that saying if I have multiple maidens, that after the first effect is used then the others cannot use their effects either?
