He can get away with those anchor placements because he uses an oblique angle of the forward cast with a pronounced rod drift to the left after the stop...otherwise he'd be getting collision loops or smacking the blank.
It's hard to pick up on, but watch how he uses the angle and weight of the loop to pop the fly out sideways from under the line.
Also notable, look at how much top hand he uses throughout the casting cycle, and the unusual key position he starts the forward cast from.
wear your eye protection kids, this stuff is not for amateurs!
