Question about Resolve Fusion Training Book

Apologies if this should be posted elsewhere.
I'm working through the Training book (pdf) Fusion Visual Effects with Davinci Resolve 16 and have got to the end of Lesson 4. As I like to try to consolidtae what I've learned I'm having a go at the practcal exercise (p107) but I am stuck and cannot see any example of the solution. Specifically

"Use a transform node to keyframe Dr Jones so he follows the same path as the biplane,
but inverted."

I can't work out any way of doing this (the inversion) using knowledge gained in the preceding chapters.

I can think of ways I might approach this (maybe using an expression and "Point"?) but this has not been covered yet and I doubt it's the solution the course tutors intend.

I'm no doubt missing somethig simple and obvious, but could anyone give me a pointer.

Still not solved this and no responses. Does no-one do the training (or at least work through the exercises)?

I would copy and paste the first Transform node and use it with the Dr Jones image. Then just manually adjust the Spline points in the Spline Editor to be the opposite of the Plane.

Ahh yes, of course.
I knew there'd be a simple answer (effectively) covered in the tutorial.
Many thanks Eric

Does no-one do the training

I didn't make it as far as the old Fusion manual. I've decided to wait for the version 17 updated training manuals.

The changes were not that drastic in Fusion. I found the old book still very useful when getting into it.
