I think it was deliberately left ambiguous. If they want, they now have a justification to bring back Parasite. If not, they can say it was just a "temporal conjuration".

Though Mr. Mxyzptlk's powers are honest-to-life reality-warping, not just illusion-making. He could have easily resurrected Parasite, then just as easily remove him from existence.
