Greymule, I don't know the answer. It just seems plausible that under a failure to retouch scenario, all bases that the runner is required to touch in order to correct his infraction are fair game for appeal. For example, in your second scenario, why would they only have to appeal at 2nd? Why wouldn't an appeal at third or home be viable? The runner failed to touch those bases when he was required to retreat. It's not the same as a missed base. It's a requirement to retouch. Seems plausible, doesn't it? Heck, the defense only needs to tag the runner himself, standing on any base. Why couldn't they just tag any base that the runner was required to touch? I don't know the answer, but it sure makes for an interesting question to ponder.
