Its a definite "yes"that Hiro will undo the effects of Universe One. Considering how Hiro is handling this arc and all of the "losses" the allied forces have suffered, everything will go back to normal when Irene dies. And yes Irene will die simply because she's the parent of ones of the main cast characters (in this case, Erza), all of whom have lost their parents for a "bigger impact" and emphasize their self-importance.
