I agree with those above that seem to think it should not be practiced. I think it is just a transitional part of the swing and you don't want to slow or pause your swing to "point the butt cap". My opinion is it happens on most swings but if you are under pressure and have to use a shorter swing, you may not even get to a position where the butt cap fully points at the ball. So, conceptually, it is OK as you will pass thru this phase on most swings but be sure to use the concept smartly. I prefer to think of letting the wrist to lay back a bit as you start to pull the arm/hand forward into contact, keep the wrist loose and without conscious adjustments into and thru contact, and then let the forearm roll or pronate into WW follow thru.
