The biggest benefit is in "long range" IO. There you use what's called "self clocking" signal forms.
This is why you don't need all your USB peripherals to be in perfect sync without having an associated penalty for frequency matching. In reality, things are a bit more complex, but in general self-clocking signal form is a must have for such applications.
