Why are California freeway exits painted with disconnected shoulder lines?

On freeway exits on a recent road trip to California, I noticed the following paint markings:

The paint marking for the exit seems to disconnect in two locations from the main shoulder paint line, as if the exit was painted after the road. However, every exit I noticed in California was painted like this, while every exit I have ever seen while living on the east coast has been one unbroken line on both sides:

This may be selection bias, but I only ever saw this marking style in California, and I traveled through several states near it as well.

What does/would cause this style of painting an exit to occur in California?

Edit: In response to a comment I went into street view and picked 10 exits at random. Here are the results:

Both disconnects (before and after exit):

Only disconnected after exit:

In particular, note the following locations where the last exit in a neighboring state does not have this pattern, but the first exit in California does:

This peculiarity on Californian highways is even mentioned on Wikipedia.

The purpose is to easier see that an exit is approaching when driving in foggy conditions. The interruption of the road shoulder line is used on highways in areas of California prone to fog.
