I think that can have a great impact on results.
If Sinner-Rune play first and Sinner wins, the second match between Djokovic and Hurkacz would be useless. De facto an exho.
If Djokovic-Hurkacz play first and Djokovic doesn't win 2-0, Sinner likely would be less motivated, and that's an unfair disadvantage to Nole.
I think play Sinner-Rune first is, at sport level, the better thing to do. So no one has an advantage by less motivated opponents(Maybe Hubi, but who cares?). But I also understand organizer can prefer two meaningful match, at least on papere.
