...because when you're going up on the vertical you are crabbing into the wind already, and reduces the number of degrees to reverse course. If you stall away from the wind, you will find your plane blown downwind and your downline will not be on center, plus the turn will more than 1.5 wingspan, resulting, I believe, in a major downgrade.

I'm sure you've already noticed how much easier it is to do a stall turn into the wind as opposed to when the air is calm... stalling away from the wind is doubly hard...
