A man in a motocross race has just turned over his motorcycle as two other riders prepare to overtake him.
A man in a motocross race overturns his motorcycle just as two other fellow competators pass him on the track outside.
If the riders are preparing to overtake him, they are in the race as well, and are therefore competitors. Overturns is a rephrasing of turned over. If they prepare to overtake him, it follows that they pass him.
