When passing args to `WP_Query::__construct` method (in this case, but creating a `new WP_Query`, this one internally executes the `WP_Query::get_posts` method and stores the result in the `WP_Query::posts` property. When calling the `WP_Query::get_posts` again, the same SQL query gets executed, and the result is again stored in the `WP_Query::posts` property.
This was introduced in <a href="https://core.trac.wordpress.org/changeset/51003">[51003]</a>.
