I've used very similar technique when standing on my tip-toes in squishy/wobbly tundra, trying to see above alders or willows. By grabbing the tips of branches from a 2-3' circle of branch tips and pulling them together into a cluster, you create a cone type of effect that helps with both lateral and vertical stability by a surprising amount. It also works with long stemmed stiff grasses. It's not very ideal, but you have to work with what you have.
It sure beats wobbling off shots with nothing more than wishes to guide them.
