Very cool!

That's because the points along those edges are not shared, there are duplicate points in the mesh on those areas. This makes it possible to do stuff like get sketch-rendering edges there. But like I mentioned above, maybe there will be a "weld" or "merge vertices" control in the future that will be on by default, and that you will want to turn off to maintain this effect.

If you wanted to remove this effect now, you could use the "merge vertices" or "weld" function in C4D to make those vertices unified.
