Looking at code briefly this seems to work as intended.
Purpose is to pin displayed image when switching between objects when switching between UV, sculpt and texture paint workspaces and objects.

But this feature is completely undocumented. Only hint is button description.

Even with pin=false, I still need to switch workspace to refresh the displayed image.
Thus, I don't think it 100% works as intends.

In programming code, perhaps, a callback is still needed :
e.g. when selected texture node changed --> notify every displayed-image panels to refresh.

The pin button also lacks documentation, I agree,
but IMHO, your edit changes the original question (image-not-refresh bug) to a different story (lack document).

The documentation is kind of there but needs to be easier to find: https://docs.blender.org/manual/en/latest/interface/window_system/tabs_panels.html
As for the issue you're talking about with the image not refreshing. You should have included that in your original post. Seeing as this one is now a documentation issue, you should create another bug report with the issue you're experiencing.

hyyou (hyyou) mentioned this in T76017: Image Pin=false , but Image Editor not refresh to the selected image node in Shader Editor.Apr 23 2020, 9:49 AM

@Alaska (Alaska)
OK, I have re-created a new task : https://developer.blender.org/T76017.
