Does that also apply to the Boeing 737 series because there is nothing I could find about that in the various manuals?
Disengaging auto brakes with manual braking requires applying heavier manual braking than the auto brakes are applying. So it makes sense that the pedal deflection would be higher for higher auto brake settings.
