The creationist definition for macroevoution is "whatever hasn't been directly observed yet". So, it is currently one step past speciation, at what they call "kinds". So a wolf can become a dog, but that doesn't mean it's related to cats, because they're different "kinds". When a change of that magnitude is experimentally demonstrated, they'll move on to saying that OK, maybe mammals, but there's no relationship to reptiles. There will always be a god of the gaps.
