Rear brake failure

The problem is air is lighter than brake fluid, so the bleeder needs to be at the highest point in the circuit to allow evacuation. It won’t matter whether you shoot air into the bleeder or the reservoir - the air will still be trapped.

That’s why you can never reverse caliper son a car. They usually fit both sides, but are mirrored so the bleeders are always at the top.

The only solution I see is to bleed the caliper off it’s mount, or raise the bikes front end until the bleeders are it the highest point in the hydraulic circuit.
I don't think so. You force fluid into the bleeder and it forces the air up and out the M/C / resevoir or at least I think that's how it works, regardless it's been working well for me.

Mostly true but if caliper has an air pocket above where you are injecting and above where the hose heads to the caliper, the fluid will happily flow and leave the air pocket untouched.
