The best analogy I know of to explain movement comes from works of Art. Still life portraits of fruit have no movement. But take a piece like 'The Scream', or the mural in the Sistine chapel depicting the creation of Adam there is not only movement but a feeling of tension as in the scream, and awe and love with the hand of God reaching out to Adam.
When I am looking at a formal upright, I don't see movement. I see balance but not movement. However when I see a windswept style bonsai I can just imagine the wind pushing and bending the tree and the tree resisting the wind.
Movement has direction or flow. In a windswept bonsai all of the branches are on the lee side and usually the tree is also slightly tilted or "broken" to show more or less the relentlessness of the wind.
A formal upright does not really have a direction. When you take a 360 view it shows balance but not much in the way of movement.
Happy gardening in Hawaii. Gardens are where people grow.
