Interesting - it looks like when the curvature is tight enough/the segments long enough, it can get trapped in a local energy minimum which is not the global minimum.
One way to nudge it out of this configuration would be to use the grab tool.
Connect the ‘Grab’ component to the {0;0} input of the Entwine, then
hold down the Alt key and use left mouse button to drag the point in Rhino.
