@StardustScream nah, the camera had panned away by the time she said the last part about matches, which is another indication of a character passing away. Most likely it was meant to be her dying regret instead. Besides, you don't survive that kind of wound that easily (unless you get aid quickly), and as I mentioned before, the whole wrapping a story such that the end equals the start is a common literary technique, which means she has to die for the end to equal the start (where we saw a black haired corpse).
She also stated she was under full stealth earlier, so only reason for it to falter would be for her to already be a corpse, just as it didnt falter until then for the black haired girl.
