All the darn time
it's exactly what is happening.
From the limited experience I've had with jumping, she's trying to jump for the horse, she's curling up or bracing defensively. It's not because her toes are pointing outwards, else MyBoyPuck would have said something. However I'm not going to disagree with you about the other points you've brought up since I haven't had experience with uprights.
I do feel, OP, that you need to try what a poster on the above thread said, and warm up in two point. At the walk, the trot, and canter. Just relax and move with the horse. Focus on keeping a deep heel instead of bracing from your feet.
I primarily work Dressage but had issues with my legs. Two point work really helped me to keep them from flapping around, or curling up.
