If SoJ wants us to believe in this backstory, then it retroactively makes Apollo not getting Machi's situation immediately into something contradictory and Apollo kind of looks like an asshole. That's not even negative character growth.
It ALSO directly shows us the consequences of Dhurke's neglect outside of the portrayal in SoJ itself; we as the players have already seen the loneliness and horror of a child abandoned in another country through Machi. If SoJ ran with that, it could have worked to try and connect that plot thread from AA4, contradiction aside...but SoJ wants you to feel sympathetic towards Dhurke. It wants to treat him as a well-meaning, if misguided father figure to Apollo, and have Apollo, as well as the player, connect with Dhurke in time for the tragic reveal. Yet, with the harm shown through Machi, we have even LESS reason to feel sympathetic to Dhurke, especially as he chose to put Apollo through that, whereas Machi's situation was due to a bad decision that he made and kept from his parental figure.
