That means nothing, especially with all the layoffs.
One thing that I learned over the years is never mystify "code quality". Maybe you can say a certain team/project produces high quality code, and maybe Google's overall quality is better than my company's (considering their bar of hiring), but you want to avoid generalizing that, especially at scale.
The average software engineer at a large company ships just enough code at good enough quality to earn a salary, nothing fancy about it.
