Her behavior seems simple to me. Her breadmaker is being that bad-ass MMA chick. Her story-line is "Redemption". UFC shuffled Holm up to give her the 145 belt, so to have an out if they want to avoid that.
Now... Ronda needs to win, that's it. The Holm loss was a mental loss, she did her rounds on the soft talk show circuit, but she ain't ready for Ariel to ask her about her busted jaw or her lack of head movement, it will mindfuck her.
So she is employing a smart strategy, use her cred with the UFC to avoid the media and stay focused. She wins, she remains that bad-ass chick, maybe she even calls Holm out for a 145 fight and holds 2 belts and then Cyborg.
She loses, she's done.
