I will say that the text that's here, on reading it, I think could be considered redundant. It's true already that a collectivity is composed of citizens, and by representing a collectivity, a government represents the citizens of that collectivity as well. For it to say “collectivity, including its citizens” would be a true statement. It wouldn't be necessary to say, but it also wouldn't change the meaning that's there already.
Again, to repeat myself from before, I think the meaning of this provision—that a Métis government represents the Métis collectivity—remains the same.
