Having said this, I don't know why the air would "want" to return to the MC. But several people have sworn it worked, FWIW.
Maybe gravity plays a part. It does explain most things we can't otherwise understand.
Having never had an issue bleeding brakes in my life ... I do not carry a 2x4 around to jam the pedal.

How does the air get out of the master cylinder once it has spawned to that point?

When you release the pedal, air bubbles that have migrated to the master cylinder and successfully negotiated the bend from the line to the compensating ports will bubble up to the reservoir.
