So we find out, that in order for tyler to break the sire bond, he has to turn multiple times, but technically he's able to turn multiple times because of klaus, because he turned him into a hybrid, so it doesn't make any sense.
Their sirbond was established do to the idea that Klaus freed them from the pain of turning(during the fullmoon). Forcing themselves to turn multiple times and experiencing that pain over and over. Made them no longer fear or dread the turn. Allowing them to no longer be grateful to Klaus. 😎
