It's essentially the same as twin turbos - usually one of them will be smaller for a boost lower down in the revs, while the larger one gets up to running speed. It just reduces lag a lot.
However, Mercedes Benz have a slightly different feel for it - they have the bi-turbo system. Just two equally sized turbos on each set of cylinders (they only have it on their V12s, perhaps V8s, but I'm not sure).
