What happens sequentially if a husband initiates Lian after accusing his wife and subsequently wishes to present evidence?

Primary text

If the husband performs Lian, thereby negating the child's lineage, and subsequently chooses to present the evidence, he is permitted to do so. Upon presenting the evidence, both the consequences of the Lian (negation of lineage) and the consequences of the evidence (establishment of adultery and its penalty) become established.
