If Rubick steals Duel and duels a target that is already dueled, the first duel to end will end both duels. This seems like unintentional behavior and the second duel should still follow through with the rest of its duration.
Steps to replicate as Rubick:
1) Enemy Legion Commander duels an allied hero
2) Rubick steals duel and duels Legion Commander
When the first duel ends, either because the allied hero died or because the duration ran out, the second duel will end as well.
