the intent part is the linear part, movement through spiral channels along the body -starting at the dantien- is a very big change in that it takes a lot of work to develop to a useful degree. To power everything that way seems to be a very long road to me.
Nicely put, Alfonso. Intent/Jin can be looked at as a laser beam that follows along the surface of the body during a movement or application; the "qi" part has more to do with the connection either through bone or 'connection' that keeps it all together. In other words, real reeling/spiraling movement is comprised of 2 basic things that work together as one ("intent" and "qi"). Confusing the two in terms of function immediately tells me where someone is in what they understand.
