No. Even though you may leave the active spot, the same card is still considered to be in play and subjected to the once-per-turn restriction. Furthermore, while there is no limit to how many times you may switch a card's board position per turn (provided you have the cards to do so), you are still only allowed to retreat once a turn, even if you don't have to pay a Retreat Cost.
You can use Turboblaze once per Reshiram, as long as you can get a new card in the Active spot. If you scoop one of them up, the game will consider it a new Reshiram and you can use Turboblaze again with that Reshiram - as long as you can get it into the Active spot.
