Dramatic effect is the best explanation I can venture for that. As much as I enjoy Heavy Rain and Detroit: Become Human, a lot of things in those games happen solely because they're dramatic, without regard to overall continuity of the plot.

From a gameplay standpoint, I think David Cage wanted Ethan to be able to show up at the warehouse and survive unless he went alone. Moreover, if Ethan always got shot and killed by Scott when he and Madison showed up together, that could create a scenario in which every playable character except Scott died and Shaun still survived (assuming Madison lost the fight with Scott at the warehouse and Norman died in "Mad Jack," "Fish Tank," or "Solving the Puzzle").
