Question about driving

​

The way Drew is lining up his shot looks he would throw an anhyzer or just a straight shot on the 14th tee but he's releasing the disc way to the right throwing power hyzer which almost looks like a slight grip lock-ish / rounding? Many tutorials teach that you should start your run up from the back left corner to the front right corner of the teepad when throwing hyzers. Are there any benefits of throwing hyzers like Drew? Have noticed that Lizotte and McBeth do this also when going for big hyzers. Thanks.
