To be sure of what? She wasn't there to kill Sabine. She was there to get the map and go.
She obviously didn't want to he facing ahsoka so got out of there, and sabine was still trying to fight even in her state. There was no reason to stick around and risk getting slowed down when she had what she came for
First off, no, they did not get hit in the same place.
Qui gon clearly got stabbled basically through the spine or close to it. Irs shown later that Sabine got stabbed in the right of her abdomen.
Finn, a male, got sliced up the middle of his back and survived. Ben gets stabbed in a similar place to Sabine and doesn't immediately die, but is healed.
Finally, Darth maul survives this. And that was way before disney.
Were past this being a problem.
