Because even the people at Microsoft do not know or understand how Windows GPO works. This is an accurate statement.It's a mess. MS can't be bothered to make proper documentations. Like Why Group policies have no effect on Defender service?
The people that write Microsoft documentation are not Windows internals gurus at Mark Russinovich's level. They're most just technical writers.
The vast majority of Windows internals is uncharted and undiscovered territory - changing as Microsoft changes the OS with every update.
