In plain words
If you claim that the reflection belongs to both together, that is incorrect, for it is not seen in both independently. Otherwise, an otherwise invisible reality would become visible, just as Rāhu's shadow is seen upon the sun and moon.
Close to the Sanskrit
If it is said that it belongs to both, no, because it is not observed in both either. There would be the visibility of an unseen existent thing, like of Rāhu upon the moon and sun.
