What is the consequence of suckling when marrying the daughter of one's paternal cousin (bint 'amm)?

Primary text

If a man marries the daughter of his paternal cousin and their shared grandmother nurses one of them as a minor, the marriage is dissolved. If the grandmother nurses the husband, he becomes the wife's paternal uncle. If she nurses the wife, she becomes the husband's paternal aunt. If she nurses both, each becomes the other's paternal uncle.
