What do you mean by "directly loading the left wrist"? Swingers use Drag Loading (10-19-C).

Mr Blake will often differentiate swinging and hitting by which power accumulators are directly loaded. Hitters directly load PP1 and swingers directly load pp2, and both indirectly load pp3. However, my confusion occurs because he will often interchange left wrist with pp2 in this regard. Others have agreed that directly loading the lag onto the left wrist, and keeping it onplane with a left hand karate chop motion is the way to swing. Doesn't work for me.

Mr. Evans has a couple of drills on his website which demonstrate lag being powered by the body or right shoulder, and warns about using the wrists. I am inferring he meant both wrists.
