So you asked a question in the thread title, then posted your own answer in your post. This isn't a serious question wanting a serious answer.
If SG jumps back, you don't have to do anything. I think the question was implying if you do anything in response to her jumping backwards, she will teleport and punish you. Which isn't true, just walk forward. If she teleports, yay you get a full combo punish while she has to recover for 25 frames. If she does anything else, like jump back air down laser, block it.
