Well, there's an argument that a roster representing every team --- and the handicaps and benefits that represents --- is appropriate if the players are fighting for an advantage which, in theory, could benefit any team in the winning league. The argument, of course, largely falls apart when the leagues have a different number of teams, however. But really, it shouldn't matter, as a competitive, high-stakes game shouldn't be filled with unstrategic high-volume bench emptying. So, no matter how much the game's counting is asserted, managers are getting other messages too, though I'm not sure from where.
