What does 2 Chronicles 21:20 mean?

He was thirty-two when he became king and ruled for eight years in Jerusalem. He died without anyone's regret. He was buried in Jerusalem, but not in the royal tombs. 2 Chronicles 21:20 - Modern Text Bible

(Jehoram's legacy is so negative that no one mourns him, and he's not even buried with the other kings—a final sign of his disgrace.)
