Clamp overlap works on the model as a whole. It just prevents things from blowing up. So for example, if your bevel once it passes from 0.25 in value, the whole model will start to collapse on itself, it’ll clamp it in that value and above that it wont take any effect, because it doesn’t want your model to get messy. So it wont matter what edge you have, it will apply that value to the whole model.
