That's my understanding of it. The requests come from different places
(same referer, different IP address).

See http://code.google.com/apis/maps/documentation/staticmaps/ --

Use of the Google Static Maps API is subject to a query limit of 1000
unique (different) image requests per viewer per day. Since this
restriction is a quota per **viewer**, most developers should not need
to worry about exceeding their quota. Additionally, note that requests
of identical images, in general, do not count towards this limit
beyond the original request.

The "in general" in the last sentence covers the case where one user
requests the same image as another, but before the earlier request has
been satisfied and the image generated. In that case, it's likely that
two identical images will be generated and counted -- but that's only
1 image out of a quota of 1000, and only for one client.
