This happens in correspondence chess. When you open the analysis board to better study your moves, you are allowed to delete moves already played (?) and then create variations to be played that doesn't match the current play.
This happened to me yesterday. By accident I deleted a played move, created variations to be played on a board that didn't resemble my match at all. Then I just lose a full piece right in the beggining and was forced to immediately forfeit the match.
