Nice, except calling the BR out for missing 1B is not a time play, it can be done anytime the ball is live. No run can score when BR is called out before reaching 1B legally. So back to the problem. If R1 goes in the dugout he can not return for a live ball appeal. If called out for abandonement and advantageous 4th out can still be called on the appeal. DC should not have called time, he should have just encouraged the players to throw the ball to 1B for live ball appeal.
