You are correct - in Joomla 4 the record was updated. In Joomla 5 and 6 a new record is inserted
I do not know the reason for the change

If you control exactly you will see that these records are different. These records are used to attach tags and articles. When articles with tags are re-stored after beeing updated, a new record is added into the umc table.
