I don’t think it covers what she says otherwise?

For better or worse, she has a free speech right to lie in public (up to the point of violating someone’s rights). She can say what she wants outside of the courtroom, apart from what limits the judge has set.

But once she’s in front of that judge, she’d better be truthful, because if she took a plea bargain, she knows prosecution has some good evidence against her and won’t be afraid to point out any lies.
