If there's not very much car traffic and almost no trucks, and if that traffic obeys the rules and speed limits well enough, there is not always the need for separate bike lane. This way the bicycles, if there are many cyclists, become an indication to car drivers that what they are driving on is a local street, woonerf, school area, etc. While the design with separated bike lane would be a 1 person wide situation, while this way cyclists can cycle 2 next to eachother together in the street which is a lot more fun. I don't know this particular street or city, if it works depends on local factors such as general driver culture, habits, local policing efforts, amount of cyclists, etc, but it's not per definition the worse design.

What I dislike is that they did put in the bike lane for the silly short piece. In this case, it could've been better to just raise the entire intersection in a speedbump-plateau and no separate bike lane at all.
