It would depend greatly on whether the cullet was formed from a mix that had actually completed it's chemical reaction Michael. If it hasn't, then it would need the sustained heat.
Not finishing the reaction, on the makers part is a good way to cut costs and pass the process of proper melting on to someone else.

The other reason would be the viscosity of the glass itself.
Where are we going and why am I in this basket?
