Swap back to your pushbike, or your legs only, mentally.
On foot you can definitely and legally turn left or right.
So its a valid junction for pedestrian routing.
On the pushie, you could do a left turn with legal risks, or do a kerb jump to
manage the left turn. Probably not valid for pushbike routing.
Now add that to the relation you are making....
