The ABS needs to be activated and while this takes place your foot is on the peddle and force withing the brake lines pushes against the wheel cylinder, the calipers and the ABS valves that may or may not have a build up of fine particulate that may release into the brake fluid and travel along and eventually be removed as you do your 2-3 year bleed.
To give you an idea of how dirty it can get take the screen out of the M/C and look in the bottom. That dirt should be sucked out before a bleed or it will be sent down and through the system and ABS where you may get a valve lock up or partial lock up.
