Hi Tim,
I've spent quite a bit of time at that intersection observing to see how it works (and doesn't work at times)
The idea behind it is that it has a dedicated walk/bike phase on Catherine. Traffic does indeed cross over but if everyone follows the light phases there are no conflicts. This breaks down if a car does an illegal turn (or continue straight) on red, or if a cyclist rides through a red "don't walk" signal and attempts to cross on a green traffic light.
I'm not sure why the bikeway crosses Catherine from north side to the south side of the road there.
I would encourage you to contact city staff for clarification and to share your concerns. Cyrus Naheedy
