You're absolutely correct. But I do believe we're talking about two sightings that are very similar. The first one (that you are referring to) wasn't covered by the MSM so it didn't get much attention. The second and most recent one was. I think the MSM lifted the pictures from the first sighting and used them for the second.
Unless they are the same one, but I haven't seen anything that suggests that. Their similarity does make them confusing, especially when photos from the first sighting are being used for the report of the second.
I'll verify this later when I have more time.
