That is
incorrect. Pole planting
does not put you in the right position to begin a turn. Stand in your living room with your poles out and see how many different ways you can reach out and plant, it can often lead to the shoulders being far too open to make an efficient turn. Also a whole load of "tipping" can take place which can lead to being stuck on the "inside" ski through the final phase of the turn-not pretty.
Ski racers are not always technically "good" either, just fast, so I guess it is probably a pretty bad reference point.
Depends what you want from skiing I guess.
