if the reservoir isn't run dry, it shouldn't put air in the system. it is just putting air and fresh brake fluid in the reservoir (which already has air in it, unless it is overflowing which it shouldn't be) and pushing fluid out of the reservoir and out through the bleed screws at calipers. as long as there is fluid to move out of reservoir air doesn't move out of it, the air pressure just pushes the fluid down.

Do you bleed the air through the brake reservoir overflow then cap it off and proceed to bleed the brakes? Spilling or splattering brake fluid scares me.
