Note that I was wondering, not about the end result (which I believe should be equivalent), but about intermediate results. These should normally not be visible for the end user, but if a query isn't optimized, it may be very, very slow, and in some cases, you might get temporary files above the limit. Which is what alerted me to this possibility in the first place.
