It's so damn easy to bleed with speed bleeders why would you want to screw with back bleeding?
Put a tube on the bleeder, stick it in a bottle, pump the brake lever keeping the mc full until the tube flows clear.
Less trouble, less chance of flushing debris into the lines / mc / abs, less mess, less chance of getting brake fluid all over.
Those videos never show that syringe slipping of and spraying brake fluid everywhere.

1. When you cannot get the system bleed the normal way or
2. When you are replacing a top line and do not want to send air down through the ABS Module.

It's my understanding that when bleeding an ABS system that fluid bypasses the ABS module, hence the need for having the module bled with the computer.
I'v done it a time or two to try it but, to me, it's not worth the risk of pushing trash back up the lines.

In 40+ years I've never mot been able to get brakes to bleed the normal way. It's been a pita a few times but never failed.

For the record, no fluid bypasses the ABS module when bleeding normally. The module is just where you can get air trapped and thus need the digital technician to move the actuators - to remove the air.
By reverse bleeding you can "bypass" the need to push air through the ABS module - problem solved.
