You're assuming that Solr is just used in these cases to index discrete web pages which Google etc. would be able to access via following navigational links. I would imagine that in a lot of cases, Solr is used to index database entities which are used to build [parts of] pages dynamically, and which might be viewable in different forms in various different pages. Plus, with stored fields, you have the option of actually driving a website off Solr instead of directly off a database, which might make sense from a speed perspective in some cases. And further, going back to page-only indexing -- you have no guarantee when Google will decide to recrawl your site, so there may be a delay before changes show up in their index. With an in-house search engine you can reindex as often as you like.
