It's a "magic roundabout" meant to be able to combine the joining of several roads into one gigantic roundabouts within roundabouts. It doesn't work very well.
Near me there's a giant roundabout joining 6 roads together, 2 of them highways, and it works fine as one roundabout. You just enter the roundabout and exit at your exit, it's not complicated and it doesn't need to be.
Obviously not a criticism of your statement, but this thing shows up every five minutes and I've still yet to see a single justification for it's existence.
And yet the best you could muster was the unfired clay being molded by an amateur having intercourse with a ghost! Clearly this desires to be a two leaf clover interchange.
