I agree it's confusing. You're right, we do interact with Google Scholar. However, the interaction must must be user initiated and the request needs to come from your browser (as opposed from our servers).
To systematically collect the citation numbers (and keep them up-to-date) we would need to request this information in the background from our servers. That's not possible, Google Scholar would block us within seconds.
If you click and view the "Cited by" link that shows the Google Scholar results, Google Scholar thinks you are using the site like a normal user would and that's ok.
We would love to have an open access data source with the citation graph of all scholarly literature. But at the moment there is none.
