I never heard of the replace one, bleed one method. It was probably covering some other problem, and that's what we have here.
If the OP actually observes that the air bubbles move backwards toward the caliper even after the bleeder valve is closed, then he has a faulty bleeder valve OR his bleeder hose is not sealing tight enough around the valve. Obviously, the end of the bleeder hose must be immersed in brake fluid, not just hanging in the air. I used a pretty cool and simple method for years using the spare tire for "power bleeding". Then I got the cool IPD unit. Even then you might have to struggle with the master cylinder sometimes. Be sure to observe the correct bleeding order: RR, LR, RF, LF on American cars.
I have a TSB somewhere that states that problems arise if bleeding is not performed after a brake pad replacement. It claims that pushing the pistons open forces dirt into the brake lines. Just a thought.

It's common sense, once you introduce air into the system it should be purged immediately or you will suffer the consequences of it moving around within the system.
