A guy showed me this method awhile back, one advantage being in that when done correctly, there is little tendency for the saw to bind, and also the big plus of the butt of the tree being held in position by the ears sticking up, until the crane makes the lift. With risks to anything close that could be damaged if the butt swings, it works very well.
I was hesitant to use it, because of the additional time involved, compared to just whacking the tree off straight across, but now that I've learned it, have come to rely on it for almost every large crane pick these days. On smaller trees, you can just leave the ears sticking up on two opposing sides.
It's enjoyable in trying to get your cuts precise, and the secret to success is after reaming through on two sides, going around to stick the nose of the saw through the reams and cleaning out the middle of the tree from each side well, so the cuts meet. When slanting down with the saw to finish it, the order of cuts lets the tree get shifted in one direction or another if necessary, depending on the position of the crane boom, and where the object that can be potentially damaged is located. Any binding is quickly relieved. Lastly, the tree can get leaned away from the vulnerable object, but still is held in position when the final cut is completed.
I have never seen anybody else using it, besides the person who showed me, and folks that I've shown it to. Some sacrifice if the wood in the butt is highly valuable, but it's really a cool method, imo. Not such great precision here from yesterday's job, but I think you can get the idea.
