Is the clinician saying that if R1 had touched 2B and then overslid and was tagged, he would be out, but because he missed 2B before the overslide, he is entitled to 2B and can't be tagged out?

I haven't done Fed in years, but either way it's an out unless Fed has made some peculiar exception (which I doubt).

To take an extreme example, what if the throw had gone into center field and R1 then missed 2B and attempted to make 3B but was tagged out. By this clinician's logic, R1 would be sent back to 2B, never having touched it and now entitled to his award.
