The $current_screen is passed as a variable to callables hooked from the current_screen hook. Before this hook, the $current_screen isn’t set up, so globalizing the variable won’t do anything anyway.

Per the code in the original question, post type support for the editor is also removed for these posts. Screen layout options are stored in a user option for each post type.
