Ah! I just saw that Darren had given an amazingly full reply before I sent my last reply! Sorry I didn't see that first before hitting "Send".
Looks like there are several reasons why the scanner-controlled ABS bleeding is preferable to the "hard braking" method, if the scanner method is available to you.

Nice summary, Countyjag.
I'll let Darren speak for himself, but upon re-reading his reply to your earlier question (about using a scanner to "automatically" bleed the ABS), my understanding is that bleeding the ABS is done with the bleed screws closed. The purpose of this step is to move the air through the ABS and into the downstream piping. Then you can proceed to regular bleeding (by pressure, vacuum, or pumping the pedal) to actually remove the air from the brake system.
I'm thinking I did much the same thing on my car by activating the ABS through hard braking followed by another bleed.
Do I have that right, Darren?
