sequence of tenses and will

Question

I'd like to know if my understanding is correct.

• She said "I will leave for the U.S."

This sentence can be rephrased in two ways, i.e.

1. She said she would leave for the U.S.
2. She said she will leave for the U.S.

If she has already left for the U.S., you say 1.

However, if she hasn't left for the U.S. yet, you can say either 1 or 2.

Am I right?
