I had the same thought process and I agree with the rest of the explanation as well. If I were on the field I'd feel like I should have called something, but I just don't see how you can directly justify any interference. This is one of those scenarios that tends to end with a MSU solution when an umpire feels like they just have to do SOMETHING.However, the interference call could ONLY occur at second base ... not with the runner coming home. So ... I still think no interference since the runner cannot be put out.
