If you have that set up so that each transition is made for its respective parameter value (let's call it x), it will move from each toggle state as the parameter changes. Each layer can only exist on one state at a time, and each state can only play one animation at a time. If I want to toggle three objects while only using x and one layer, I would need a state for every combination of toggles, States 1-6. I would then need a separate toggle button for each value of x, 1-6.
This method is the better option if you want your toggles to be mutually exclusive, but if you want to be able to mix your toggles, it's just too messy compared to using different params and layers for each toggle.
