Some visualizations work for some people and not others. That's why it's important to train with different teachers/coaches until you find one with a model that has a good success rate. At my level I tend to favor concrete simple visualizations that lead us to experience tangible physical changes in our bodies, rather than the more abstract stuff.

I also like the idea of unbalancing uke via application of two or more forces simultaneously. That said I would not use my own hip as a driver or for unbalancing effect as seen in most ikkyo omote, kokyunage, etc. Moving from the hips or swinging the hips in any particular direction causes a lateral loss of power in our structure (that's just the way we're made). I personally prefer to keep hips stable as you move like in kenjutsu.
