Does swearing an oath not to eat a specified item break if the item is eaten after its essential nature has completely changed, resulting in a new name?

Book of Expiations
Primary text
If the components of the object swear upon are entirely transformed and the name changes, such as swearing not to eat an egg and it hatches into a chick, or swearing not to eat wheat and it becomes a crop that is then eaten, the oath is not broken. This is because the original substance has ceased to exist, and its components have transformed, as is the ruling if one swears not to drink wine and it turns into vinegar, which is then drunk. This is established by analogy.
