I think (and I'm really no expert) the IMA in your Insight is very similar to the 2nd gen Civic's IMA setup. When you want to 'coast' the car either goes into neutral, or the engine cams basically use a vtec mode that allows to engine to pump but never compress air. This vastly reduces pumping losses but still allows EV propulsion, however there is still drag from rotating the engine.
