Temple Gate bike crossings

we are not entirely sure what the rights of ways of this cyclist-only junction in the middle of the temple gate roundabout ,-close to templemeads railway station-  actually are.

In the photo above, the camera may be taken from a path to the right which has priority over bicycles coming from the left or far left. But look at that far left approach it's on the wrong side of the pavement. And the oncoming route is meant to give way -but give way to what?
 
passing cyclists seemed to go by with no  respect for the rule of the highway code at all.
