In Street Fighter Alpha 2, didn't Rose actually get to Bison and beat him, but he reverted back to normalcy after the fight and she thought her work was done?

Her ending says she consulted her tarot after feeling uneasy about it a few weeks later and she thought that Bison was back, so the only thing she could do the next time around was kill him. In the next game, she goes after Bison with the intent to kill him, and the purity of her powers is gone and Bison taunts her saying that their powers are the same, and she realizes this at the very end of the fight and gets mauled by Bison. I think Guy picks her up and takes her away, though.
