Occasional tool paths drag through stock when moving from one contour to another

I was playing with the Nester script and generating CAM toolpaths for a test project (nothing I intend to actually build), and when I simulated the CAM toolpath I noticed something that I have seen before - sometimes the path seems to not retract all the way above the stock and drag partially through the stock when traveling from one countour to another.  In this example this only happens in one place where you can see a vertical line between the two rectangles on the right.  All the other travels for this model seem to retract just fine.

I've attached the f3d file for this model.  Is this something I'm doing wrong or maybe a bug?  Since it only happens in one spot I don't see how it would be user error, but who knows.
