[Python] OpenCV OCR with AutoHotkey Continues Clicking even after Text Disappears

I'm working on a simple autoclicker using AutoHotkey (AHK) v1, OpenCV Python, and Tesseract. The script works perfectly when I test it, for example, when I type "blood wolf" in Notepad, it successfully detects and clicks the text. However, when I remove the text, the script continues to click. Does anyone have insights into why this might be happening?

ocr_scan.py

import cv2
import numpy as np
import pytesseract
from PIL import ImageGrab
import sys
import os

target = sys.argv[1].strip().lower() if len(sys.argv) > 1 else "blood wolf"
memory_file = "last_coords.txt"

# Grab full screen
img = np.array(ImageGrab.grab())

# Convert to grayscale
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

# OCR full text
full_text = pytesseract.image_to_string(gray).strip().lower()

# Only continue if full target phrase is present
if target in full_text:
data = pytesseract.image_to_data(gray, output_type=pytesseract.Output.DICT)
for i in range(len(data['text'])):
word = data['text'].strip().lower()
if word == target.split()[0]: # use first word to locate
x = data['left'] + data['width'] // 2
y = data['top'] + data['height'] // 2
coords = f"{x},{y}"

# Save to file temporarily
with open(memory_file, "w") as f:
f.write(coords)

print(coords)

# Immediately clear memory after returning
os.remove(memory_file)
sys.exit(0)

# If not found, clear memory just in case
if os.path.exists(memory_file):
os.remove(memory_file)

print("not_found")


and AUTOCLICKER.ahk
