Hi Mike,
GP doesn’t do anything at all when it comes to the title – we don’t even have a <title> tag in the header file as it’s against the rules on WordPress.org now.
GP simple declares support for the title tag like this: https://make.wordpress.org/core/2014/10/29/title-tags-in-4-1/
This gives WordPress full control over the tag, which plugins like Yoast can then filter and change.
