Brake Flush without Disconnecting ABS

Brake Flush without Disconnecting ABS
Hi All,
I just finished a brake bleeding job with the Motive Power Bleeder on a 2011 G37 a few days ago. I stumbled a crossed the FSM and see that there is a caution warning of "Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) connector or the battery negative terminal before performing work." I realized i did not do this step, and am wondering if I have done damage to the ABS unit with the pressure executed by the Motive Bleeder. I am also curious what is the purpose of disconnecting the ABS before bleeding brake?
Any inputs would be appreciated. Thanks.

Have help and a small box end wrench - bleeding takes 15 minutes, flushing more like 30.
Have no help? Buy speedbleeders and pressure bleeder..
The pressure bleeder just replaces the helper's foot on the pedal. Speedbleeders keep it from sucking air back in while you run around doing all the things.

@rotarymike My concern doing it the traditional way is having to fully or almost fully depress the brake pedal. During normal driving the pedal doesn't get depressed to that extent. So what happens to the brake master when it's bottomed out like that.... Premature wear¿? Pressure bleeding eliminates this possibility. No need for a helper either.
@PNW_IPL The clutch is so easy to do with gravity bleeding. Takes maybe 15 min. Finish off with a few bleeds the traditional way.
