There's no mention of Google at all there. While the seventh employee at Google was indeed someone named Amit Patel, I'm having a very hard time linking the identities together.
Update: I wasn't able to associate any online identity information with the Amit Patel that was Google employee #7. Best I could find was references to a venture a few years back called Sunfire. Pretty sure he isn't the Amit Patel of Red Blob Games and Stanford fame. The latter probably threw off a lot of people, since Stanford CS and Google often go hand-in-hand.
There's even another Amit Patel that currently works at Google, but he's a supply chain guy.
As another thread confirms, it must be a quite common name:
