There are two issues here. One is that Identify shows the positional_accuracy, while the observation page shows the public_positional accuracy – this has been reported previously.
The second issue is the public_positional_accuracy seems to not have updated automatically when the observation became unobscured. This used to happen, but was fixed a couple years ago. I suspect that the issue with this particular observation is that it was unobscured before the fix was rolled out.
