Well, according to the card - it states that after the move is used, you replace all Energy back in your hand. The defending Pokemon will be knocked out after your opponent's next turn - this meaning that this scenario will work, once the move is used - regardless of you, Absol, is knocked out.
Think of this move like Perish Song, those Pokemon who stay within the 3-turns of which the move is used, will be knocked out, unless a Pokemon is already fainted or switched out. In this case, the move only works for the opponent, and lasts 2 turns (as it will be knocked out after the end of their next turn).
This is the most logical assumption I can think of, and I'm 90% sure this is the intended scenario.
Hope this helps! :)
