Why does Googlebot traverse a newly added site in ascending order of url-length?

@drew 

Googlebot crawls websites in an ascending order of URL length to ensure that it can discover the site's important pages first, such as the homepage and key category pages, before it moves on to less important pages. This crawling strategy helps Google to quickly build a complete and accurate picture of a website's structure and content, so that it can better understand how the site is organized and how its pages are related to each other. By crawling the important pages first, Googlebot can also identify and prioritize which pages should be indexed and displayed in search results.
