According to Echidna, the Return by Death is powered by Satella's delusions of love for Subaru....

....But could it also be powering Satella's own immortality? Its just a theory, but the time manipulation involved in returning by death might be effecting Satella as well, which means no matter what happens Satella can't die for good while her delusions are giving the Return to Subaru.

In the same way that Pandora can reverse her own death, my guess is that Satella's power is preventing her from dying while the Return By Death is still viable..
