No, I don't think it resets the FRO to 100%, but the feedrate is controlled by the spindle rotation when G33.1 and not by the programmed feedrate compensated by the FRO like it is with normal motions commands like G0, G1 etc., because the axis follows the spindle rotation when G33.1, so the axis will go with the proportinal speed the spindle rotates, so ofcourse it is not overridable as it would immediately cause a broken tapping tool.
