This is an area which has two ways instead of one:

Here is an route example:

Without two ways you would be routed directly to the end point, but
with two ways you will be routed with the needed detour. It's
especially interesting if you go by bike but then it's more of a
psychological divider than a physical (which is another story).

I don't like mapping like this, but I'm pragmatic and it does solve a
real problem, so I decided no to fight Markus on this.
So what is the recommendation for mapping this.
