When I have seen two very similar 360 shots from the Google Streetview car it was clear that they were from the car driving in opposite directions. Please check if that could be the case here too.
Then your only option is the general feedback route. Using Your opinion on Maps after first returning/zooming out from the Streetview. Please include the url of the place in your text feedback. And maybe even links to the duplicate streetview pics.
Sorry for not fully understanding your issue in the first place.
The way Street View is captured both for Google, their Contractors and even for Local Guides using the Street View App is that the data is captured in a video stream. This then is split into many individual 360 images. From most contributors these are a minimum of 2 to 8 meters apart. The Google Street View is much higher resolution and individual spheres are often much closer in built up areas.
If you are asking that why do Google contribute this way when you as a Local Guide cannot without being penalised by your images being made private and loss of points then I would suggest that Google own the product and can do whatever they want, they can also set the rules that you can I must follow @2be4all that is simply reality.
