I do agree with what you are saying but you need to read further in that rule. The next line states that if all runners, including the batter-runner, have advanced at least one base when an infielder makes a wild throw on the first play after the pitch, the award shall be governed by the position of the runners when the wild throw was made. The thing we are discussing all boils down to the umpires judgement on when the throw happens. This obviously does not make this 100% wrong when it is a judgement call. It is at least a 50% chance it is right because it is a judgement call that is in the rule book.
