No, it doesn't. The weight given is for 2000 letter-size pages, even if you're buying a different size.
Thus it is the weight (or, correctly, mass) of a fixed, standard area of that particular paper, even though the area is only implied. Four reams of legal size would indeed weigh 25.5 pounds, but the four packages would be marked "20 lb (75 g/m^2)." Without that consistency, how would you know you were getting the right paper (without using a calculator)? Letter and legal size are not, by the way, the same as quarto and foolscap. As I do mostly duplex (double-sided printing), I use 90 g/m^2 (24 lb) paper, with a brightness index of 96 (almost perfectly white). It's closer to opaque than the more common lighter weight paper.
