Unless you fly quite high, you will be doing your auto to whatever is in your immediate line of sight when the engine quites. For the 300 to 700 foot crowd, the average helicopter pilot will be lucky to get everything all gathered up and into a steady state by the time you are ready to flare. The last thing on your mind will be the stupid ideas that some guy dreamed up for one specific circumstance and has no sane way of proving valid. You would be better off concentrating on getting your straight-in autos respectable (that means no torque/temp spike when you roll the throttle up in the flare) or better yet all the way to touchdown with very little need for massive collective pull at the bottom. Then practice some 180 autos just for times you have a favorable landing area or favoring winds fromteh tail AND you have enough altitude to accomplish the turn.
Engine failures are called an emergency for a reason, why complicate it?
