I happen to know Mr. Ross, and I have a great deal of respect for him. Although I was not there and didn't see the call, here is what I think about it. The assistant on the mat could certainly offer his suggestion as to what may have happened but ultimately the head referee on the mat has the final say so.
I think the most important aspect of this situation is that the RIGHT call was made. So IF the wrestler did indead step out of bounds and it was missed by the the head official in the match but was later correct to the the right call, isn't that the most important thing? I mean everyone complains about officials who miss calls or make the right one, and here is a guy just trying to do the right thing and make sure it gets called right, and you are blasting him.
All in all it shouldn't be a controversy at all. Either way you look at it, either the actual deserving wrestler got to go to state on one side, or someone who shouldn't be at state would be going because of a potential missed call. I believe its in everyones best interest to just let this issue die knowing that the wrestler who should have won, did, on that night. Hey folks its wrestling and this is what makes our sport so tough!
