It doesn't matter now. After the close of competition on Sunday the whole question was moot and actually the Rules of Golf themselves make it that way for obvious reasons.
Apparently Will Nickolson was the Official in Charge of Master's Tournament Committee and as such he had the final call on any dispute in that tournament. In a sense he's in the position Bob Jones once was as the one who ran the Masters Tournament Committee.
Jones could've made a different call in that De Vincenzo controversy and all the USGA officials on site knew that. That situation was a judgement call within the context of the Rules as those USGA officials at the Masters knew and interpreted them with Jones making the final decision. Jones asked them to search the rules and if they could just find him the slightest interpretive loophole within the rules he use it to not penalize De Vincenzo. So they took about an hour and searched everything and came back to Jones and told him they couldn't find a single legitimate loophole and so Jones said;
"Well, OK then, I've got to penalize him."
H.W. Wind wrote about that incident involving the Masters, De Vincenzo, Jones and the USGA officials on site as a great example of things done and resolved correctly--in the spirit of the game and the way the rules work and are supposed to work. As we know our own sometimes contributor, Kye Goalby's dad ended up winning that Masters!
