Tried to create my first script to save all open files and while it works, I've encountered a strange issue.

Code:

#!/usr/bin/env python

# Author: DoggoOfSpeed

from gimpfu import *
import os


def save(image, path):
   for layer in image.layers:
       image_name_clean = os.path.splitext(
           os.path.basename(image.filename))[0]
       full_path = os.path.join(path, image_name_clean + '.xcf')
       pdb.gimp_xcf_save(0, image, layer, full_path, full_path)


def save_all(path_type, custom_path, x, y):
   open_images = gimp.image_list()

   for single_image in open_images:
       location = os.path.dirname(single_image.filename)
       location_parent = os.path.dirname(location)
       if x == 0:
           save(single_image, location)
       elif x == 1:
           if not os.path.exists(location + "/Saved"):
               os.mkdir(location + "/Saved")
           save(single_image, location + "/Saved")
       elif x == 2:
           if not os.path.exists(location_parent + "/Saved"):
               os.mkdir(location_parent + "/Saved")
           save(single_image, location_parent + "/Saved")
       elif x == 3:
           save(single_image, y)
       single_image.clean_all()


register(
   "save_all",
   "Save All",
   "Saves all opened images",
   "DoggoOfSpeed",
   "DoggoOfSpeed",
   "2023",
   "<Image>/Save All Images",
   "RGB*, GRAY*",
   [
       (PF_OPTION, "path_type", "Save Path", 0, ("Next to Original",
        "In Sibling Folder", "In Parent", "In Custom Folder")),
       (PF_DIRNAME, "custom_path", "Custom Path", os.getcwd())
   ],
   [],
   save_all)

main()

For some reason, the function save_all() receives 4 arguments instead of the 2 requires (I added the variables x and y to accommodate that). Not only that, those variables actually contain the data from the PF_Option (in y) and PF_Dirname (in x) when I'd expect them to be in path_type and custom_path respectively. So my question is why and how do the 2 unwanted parameters appear there?
