Why everyone else, most of whom have probably not read the book, should deliberately not answer your question and post all sorts of stuff relating to spinning is anyone's guess.

If I may take a guess, could it be because the original poster made a statement:
Indeed any good instructor will teach; Full rudder then pause (to take effect) then elevator.
and others wished to add their very valid experience to the debate.
I personally feel that this is a little more interesting than:
High Wing Drifter - No
2Donkeys - No
Flik Roll - No
etc.
and a great deal more useful.
Only a thought.
