[Python] Unable to recreate python wand composite command in wand which works in imagemagick...

I am trying to composite a small overlay image in middle of screen vertically, but at a fixed position down from top.

It works fine with imagemagick

base.png

over.png

composite --version

composite -gravity north -geometry +0+50 over.png base.png output.png


then it works and i get an image like following

composite

However, if i try it in wand, my code looks like

pip list | grep Wand
Wand 0.6.13

def main():
with Image(filename ="over.png") as o:
original = o.clone()

with Image(filename ="base.png") as b:
base = b.clone()

base.composite( operator="over", image=original, gravity='north', arguments="+0+50")

final = base.clone()
final.save(filename='output.png')



The geometry in arguments is simply ignored, and the overlay is north, without any offset.

overlay bad

i have read extensively the imagemagick, wand documentation and tried to read the wand code, or find examples online of people using it, but i am not clearer why imagemagick is not picking up the geometry arguments.
