meaning of "hadn't"

[KLPNO]

Hello everyone
I'd like to ask about the meaning of "hadn't" in the following passage.

"This is difficult," she admitted. Then with a deep, soul wrenching sigh, she added, "I wish I'd done what you've done."
But she hadn't, of course.
"If I stay here, I'll die here," she told him and every other person in earshot. "But I'll ask you, Jopale: Is there any way I could travel with you?

By saying "I wish I'd done what you've done" she is referring to his departure -- this man is leaving his homeland.

But what's the meaning of the author's remark "But she hadn't, of course"?

Does "she hadn't" mean "she hadn't done what he had done"?

Yes.

She hadn't left, like him, 'all' those years ago.
