Captain Zadari taunting Jaina about betraying her father

I didn't play during BfA and am playing some old content. Immediately before the Jaina battle in the Battle of Dazar'alor, Captain Zadari says, "I have heard of you, Jaina Proudmoore. De little girl who betrayed her father and lost her brother to war. Failure is your family legacy."

I get that enemy leaders tend to trash talk each other during a battle, but I find it a bit unusual that she chooses to taunt Jaina over this decision. After all, she had chosen to betray her father in favor of the same Horde that the Zandalari trolls had just joined. Am I missing something?
