M561 affect on M671?

Does M561 have any affect on the machine after I have used M671 to calibrate the Z towers?
I just want to make sure that M561 doesn't wipe out any adjustment that M671 applied after probing the 2 points near the z towers.
What I've setup uses M671 after a Home Z, and then performs a Home Z again after it does the 2 point probe test. Under normal operation this should be fine. My question is more along I have setup a new M671 in my bed.g file for the Manual Bed Leveling Assistant along with 3 points near the screws. In this bed.g, is it safe to have a M561 before I issue a new M671 or does that undo whatever correction was made during my Z homing?
Here's what I'm using, and I'm fighting with the front right screw after a G32, so this has me wondering if M561 is erasing the corrections made when I had M671 adjust the independent motors on the Z.
