That is a common practice with airplanes and some farm machinery where the master cylinder is way above the wheels. When you pump fluid in the wheel cylinders, you push the bubbles up into the master cylinder, the same direction that they tend to float. It can take a lot of fluid to push bubbles down from the master cylinder to the wheel cylinders when the wheels are 6 feet down on a combine harvester.
The down side of this method is that you can push dirt from the wheel cylinders up to the master cylinder. That can be a very bad thing, because master cylinders and the other stuff up there is much more complex than a wheel cylinder. On my Mercedes I bleed the brakes pumping from the master cylinder to get clean fluid into the wheel cylinders as well as get rid of bubbles.
