(At the beginning of each player's attack phase, if this card is on the field, you may move this card to an open monster area.)

Attack Phase: You may declare an attack towards your opponent's monsters or to the opposing fighter using monsters and/or the item on your field. The player who starts first may attack on his/her first turn! (More details in "During the attack phase".)

I'm pretty sure you can't move both to the center on the same turn. A new attack doesn't necessarily mean a new attack phase.
