What are the “unsafe” conditions that would permit the operator of the bike to operate the bike differently as noted above?

The statute lists a few examples of conditions which are not exhaustive: “fixed or moving objects, vehicles, bicycles, in-line skates, pedestrians, animals, surface hazards or traffic lanes too narrow for a bicycle and vehicle to travel safely side-by-side within the lane”. The statute appears to state that there may be times that a roadway permits the operator of a bike to ride a bike in the middle of the thoroughfare provided there would not be sufficient room for both the bike and the motor vehicle to ride side by side.
