While I think he is very mistaken on a few counts, what he is referring to is not completely made up, it comes from a mishnah in Sanhedrin (73a) which reads, (sorry I do not have Hebrew on this computer) “v’eilu hem she’matzilin osan b’nafshan, harodef… achar hazechur, v’achar na’arah hame’urasah”.
