Tom, by your logic, every checked swing that is called a swing is the reversal of a call; and since it changed the count, it put the batter in jeopardy, so it must be overruled by the plate umpire. In fact, every request for help on a missed tag, bobbled ball, pulled foot, etc., must therefore be disallowed and undone under your interpretation of 10-3-C; it is a call, that is reversed, and someone previously ruled safe is now out, or someone previously ruled out is now safe. Obviously, the reversal would have put the team that loses at a disadvantage, and in new jeopardy.

Consider this play; swinging bunt, F1 fields, makes a sweep at BR, BU calls "out". OC asks if he is sure, that at his angle, clearly a missed tag. BU questions PU, who advises missed. BU rules "safe", based on new information.

And, the defense made no further effort to complete the play; and DC now argues his defense was in jeopardy, as they had plenty of time to complete the out; the BU call made them think no further play was necessary. Reversal of a call, someone was in jeopardy, now. How do you want to apply 10-3-C now? Call the safe runner out? Do-over? No!!! You fix only what MUST be fixed when you left one team NO chance to be right. They live with the result of their play; F1 knew she missed, needed to complete the play, since it COULD be overturned.

The act of an appeal is a legal act under the rules, and the result is, therefore, anticipated. The act of asking for help is covered under the rules; and the result is anticipated, that someone loses because the call may be overturned to get it right. ASA 10-3-C is for unanticipated results. Not allowing the appeal is a cop-out, since 10-3-C is not the appropriate remedy. Running (playing) out the play is the appropriate remedy, because plays (particularly checked swings) can be appealed.
