The commentary explains that Merib-baal, Jonathan's son, is the same person known as Mephibosheth in the book of 2 Samuel. Scholars note that names containing 'Baal,' the name of a pagan deity, were sometimes later changed to 'Bosheth,' which means 'shame.' This was likely done to remove the association with idolatry, clarifying why the same individual has different names in different parts of the Bible.
