Also, the image shows the photos clustered to prevent noisy overlapping of the icons, so their position has been combined, averaged, and possibly shifted so that they display better. You would have to check the individual photos’ data to have a better idea.

That’s true based on my Instagram test with my iPhone. But those groups show a general area averaged for a zone. So it works in this context. Each image will have the specific geotag gps info that shows where he walked in that zone.

Actually, it is. We don’t know what Instagram does with location data, and whether it stores exactly what it is given, and whether the API is returning the same data it received. For reasons of speed and storage space they may be storing something like a geohash and their stored value and/or API response might be a lower accuracy representation of that location.

According to the Instagram SDK for the iPhone, it simply passes the location_id from the phone. I didn’t spend time with the Android which I assume has minor differences. But to assume it is geohashing when the sdk and Instagram notices and interviews say geotag pretty much point to geotag.
