I also thought this at first, but it was his second time visiting that station: there are two stops by Milford's supercharger in the vehicle logs and the claims are about the second, so he is potentially familiar with the area at the time.
I'm pretty sure they were talking about the first visit to the Milford supercharger. In fact, he can't have driven around the parking lot for 10 minutes before charging on the second visit, since the Model S was delivered and initially charged on the back of a pick-up truck - Tesla haven't challenged that part at all.
