Casebook error?

[Topshelf]

I was advised that 3.5.11 Situation A was an error because there was no rule support for the ruling.

The play reads: "It is third and 8 from A's 45 when A1 throws an incomplete forward pass. Erroneously the ball is spotted at the 50 and K1 punts the ball into R's EZ. Following the down, the R captain requests a time-out so the coach may discuss the misapplication of the rules with the referee. RULING: Since the spotting of the ball was part of the previous play, it is too late to make any correction. The error had to be recognized and correction made before the ball was snapped on 4th down."

What is the correct course of action by rule?
