Threshold range lower value script vs GUI

hi, I am using a python script to threshold an image after first testing in the GUI.
I am noticing that the threshold behaves differently ( different results) between the script and when doing threshold in the GUI.
The pain reason I think is that the Lower bound of the threshold in the GUI seems to be updated automatically. How can I recreate this in a script ?

segmentationNode = slicer.mrmlScene.AddNewNodeByClass('vtkMRMLSegmentationNode')
segmentationNode.SetName('Segmentation_Image')
segmentationNode.CreateDefaultDisplayNodes() # only needed for display    
segmentationNode.SetReferenceImageGeometryParameterFromVolumeNode(inputVolumeNode)
addedSegmentID = segmentationNode.GetSegmentation().AddEmptySegment("Segment_BBs")

# Create segment editor to get access to effects
segmentEditorWidget = slicer.qMRMLSegmentEditorWidget()
segmentEditorWidget.setMRMLScene(slicer.mrmlScene)
segmentEditorNode = slicer.mrmlScene.AddNewNodeByClass("vtkMRMLSegmentEditorNode")
segmentEditorWidget.setMRMLSegmentEditorNode(segmentEditorNode)

segmentEditorWidget.setSegmentationNode(segmentationNode)
segmentEditorWidget.setSourceVolumeNode(inputVolumeNode)

# Thresholding
segmentEditorWidget.setActiveEffectByName("Threshold")
effect = segmentEditorWidget.activeEffect()
effect.setParameter("AutoThresholdMethod", "Maximum entropy")
effect.setParameter("AutoThresholdMode", "SET_LOWER_MAX")
effect.self().onApply()

Thanks
