Video of the proposed Partial Cloverleaf Interchange in Illinois

I have never seen these "Partial Cloverleaf Interchanges" before in my life, and they are being proposed for an interchange off of one of the biggest highways in Illinois. Here is a video I found explaining how they work.

The video was posted to YouTube just a couple of days ago, and it seems like its purpose is to show that even the largest of Semi Trucks shouldn't have any major issues with the proposed Partial Cloverleaf Interchanges off of I-90 near Marengo, IL.

I have never heard of or seen these Partial Cloverleaf Interchanges before in my life, and I have been driving for almost 16 years, and I taught drivers education in the suburbs of Chicago for almost a year out of college! They basically seem like a roundabout only there isn't 2 or 4 exits on it but 3 exits, but when you Google "what is a partial cloverleaf interchange" Wikipedia.org says it is just a modification on a cloverleaf interchange, those are the almost circular interchanges you use to get on and off the highway.

I think what confuses me the most is that cloverleaf interchanges are right alongside the highway, what is in this video is you take a ramp off the highway then come to basically a roundabout which leads you off the highway, back onto the highway in the other direction, or back on the highway in the direction you came from.

I feel like I'm not the only one who can be slightly confused by this right?
