I'll pass on what I find to be a very successful technique for solo brake bleeding, along with the rationale behind it. Run the bleed hose from the nipple UP and over the tire, and then down into a jar with fluid. Air caught at the nipple typically remains there if the hose runs down, continuously being drawn into the cylinder when the brake pedal is drawn back after pumping down. With the hose running up, the bubble is drawn up by gravity (fluid down = air up) even without pumping, and the effect is aided by pumping. When pumping, the air immediately rises, and gets away from the potential for re-entering the cylinder. The column of fluid in the hose above the cylinder also applies a bit of pressure to keep any air leaks at the nipple threads from allowing air to enter from that location.
