I think that has more to do with Maya knowing Josy so well, and realizing that Josy is emotionally insecure and the jealous type. I beleive Maya wants the throuple to work out and is worried that too much time spent without her will hurt her feelings. Maya is in general more emotionally aware and confident of those feelings, despite her general lack of trust which she admits the MC overcame when he gifts her the tv and she tells him she'll never doubt him again.
Honestly I've always prefferred Maya to Josy despite liking them both, it was cemented for me when I did a throuple rejection path, when you walk Josy back to her dorm she gets upset and yells at you for not trying harder to make things work the previous night. When MC confronts her about not speaking up herself, she tells him she was scared of ending up alone. She comes off in my opinion as being more concerned with herself than the ones she supposedly cares about. She's even willing on pretty much every path to try and seduce the MC, yet the only conversations I can recall them having are the date in ep1(?) and in the pool when she gives the MC some financial advice about his inheritance. This to me implies she more concerned with sex than anything real about him.
