Can a retired runner be appealed?

[greymule]

In theory, a runner could be out four times. Abel on 3B, 2 outs. Baker hits a ball off the fence and is out at home for the third out. Defense appeals Baker's miss of 3B for the 4th out, his miss of 2B for the 5th out, and his miss of 1B for advantageous 6th out.

However, it may be that since the misses at 3B and 2B are not advantageous (they don't nullify the run), they would not be recognized. But I don't think that appealing a non-advantageous base would prevent an appeal at the advantageous one (1B in this case).
