It is according to the logic only.The logic only opens the Xbleed automatically when APU BLEED is on otherwise it remains closed. When engine fails the XBleed remains closed.That's why if fire button is not pushed you get a ECAM "If performance permits X bleed open". Engine relight procedure wants to use Iive engine bleed if wind milling is less. Since the X bleed does not automatically open it asks you to open manually.
