By applying the force out on BR at the time of the appeal you keep the force out on R1 and get a force out on BR as well.

Yes, but I think you're missing the point of the rule. It specifies that whether the out is a force or not is determined by whether it is a force at the time of the appeal. This is different from baseball, in which whether the out is a force or not is determined by whether the runner was forced at the time he missed a base. But in either game, the BR would always be "forced" before reaching 1B safely.

In ASA, once the batter has been put out, there can be no force plays, even on appeals for missing bases. And once a following runner is put out, there can be no force plays on preceding runners (except in rare cases where a runner for whatever reason retreats on the basepaths and reinstates a force play).

The following plays show the difference between ASA and baseball:

1. Abel on 3B, Baker on 1B, one out. Charles get a hit down the RF line. Abel scores, Baker misses 2B and goes to 3B. Charles is thrown out at 2B trying for a double. The defense appeals Baker's miss at 2B, and the umpire calls Baker out.

In ASA, because Charles has been put out, the force at 2B is removed on Baker. Baker is out, but since the force was off at the time of the appeal, Abel's run counts. In baseball, because Baker was forced to 2B at the time he missed it, Abel's run would not count.

2. Abel on 3B, Baker on 1B, one out. Charles hits a double but misses 1B. Baker misses 2B and goes to 3B. In ASA, to nullify Abel's run, the defense must appeal 2B and then 1B. If they appeal 1B first, the force is removed on Baker's miss of 2B. In baseball, the order of appeals would not matter in this case, since both runners were "forced" at the time they committed their infractions.
