To play devil's advocate, I think the point with the 4 dom point requirement is to show that she's completely caved in and not even protesting, ever, his 'choices' and 'actions' with her.
I mean if she had any sort of backbone, she'd not have tolerated his shit at any point, especially when he basically just bends her over and she meekly stands there and let's it happen. Some might say she was in 'shock' but I'm sorry, people don't freeze in shock and let themselves be basically raped, not if they actually have mental fortitude.
So yeah, she's basically a slut with Tony, using other excuses to do what she really wants to do, which is be a piece of ass to be used and abused and she likes it because that's how porn games work.
