Oh how I feel your pain bro
Yes, in all likelihood that teacher has no idea what she's doing.
Mentioning techniques is a critical part of analyses and you can't score too highly without it, but it's
a part; the impact upon readers and the author's use of language, positioning of the issue is technically more important, and it's where most of the marks are.
This teacher might genuinely believe listing devices is the easiest way to get marks, or, more likely, she might have felt the majority of the class was struggling with this component of the task, so wrote a piece that demonstrated how to describe EVERYTHING in the article in different ways

I don't know, I haven't read either piece, I'm just trying to make sense of this...
On the other hand, you don't get 5/20 for neglecting one (relatively minor) part of the task. Were there any other comments on your student's essay? Maybe her expression lacked clarity and so everything that she did right came across as convoluted, or didn't come across at all?
Either way, ultimately this teacher will be marking her SACs all year, so it might be best to tailor your tutoring accordingly. Teach exam tactics (ie. the right way) on the side, but for SACs focus on adapting the teacher's advice into something more manageable.
My sympathies to you and your student, this is a shitty situation to be in for any subject, let alone one so subjective
