If you select recalculation it will try to get you back to the course at the point you deviated or at some point further along in the course. I can't really say why it does one or the other, but I've noticed that it is variable. Generally, however, I just pause, and let it pick up once I get back on track, so to speak. I suspect that the likely next gen Edge 8xx and 5xx will do this as well.
