This is one of the few times I was able to relate to Rhea's character and understand her. I guarantee they didn't tell her what to say and she just improvised something because she's never allowed to be this way on TV.
I'm noticing that outside the ring, whenever she's asked questions, she does a great job of staying in character and selling whatever storyline she's in. Someone asked her if she hated Dominik while she was working out on IG and she said she didn't. She was proud of the man that he became and she wanted him to learn to stand up for himself. Turning on her didn't erase the memories of their relationship. She tried cutting a similar promo in that video you posted and I don't think the fans understood where she was going with it.
