So, King Zog claimed to be descended from the Kastrioti through his mother's side, legitimizing his claim to Skanderbeg's legacy. It's important to remember that when Zog came to power, this was the first time Albania had been independent since some years before the death of Skanderbeg. However, Skanderbeg had a son, Gjon II Kastrioti, who briefly inherited his father's title as Lord of Kruja and continued to play a role in Albanian politics for a time. Although he never successfuly re-established the Kastrioti Principate as an independent "Lord of Albania", the "Son of Skanderbeg" was significant enough for Zog to acknowledge him as "Skanderbeg II".

Given that Zog did indeed claim to be descended from the Kastrioti, acknowledging Gjon Kastrioti as a predecessor would presumably also have emphasized that he did not merely claim to be the spiritual successor of Gjergj Kastrioti, but a physical descendant.
