Autoloader finds files from other plugin

I tried using this autoloader on a plugin I'm working on, and besides loading the files from my plugin (when my classes are instantiated), the autoloader will include (and fail, but since it's using include_once instead of require_once there won't be an error thrown) other classes.

I have WooCommerce installed and I can see these files included:

public_html/wp-content/plugins/my_plugin/class-woocommerce.php
public_html/wp-content/plugins/my_plugin/class-wc-structured-data.php
public_html/wp-content/plugins/my_plugin/class-jetpack-omnisearch-posts.php
public_html/wp-content/plugins/my_plugin/class-wc-shortcodes.php

Which don't exist in my plugin ofc.

I tried adding a str_pos( 'my-plugin-slug', $fully_qualified_path ) check, but this fails for some reason.
