The door for limited spaces is wrong, it will open but not close, as there will be no way to get the door out that corner to close it with that linkage, it would need something to push at right angles to get it out the corner, and once moving it would close OK.

Actually if you look at the mechanism driving the door, there is a pivot joint and off set connection to the linkage, so when closing the door it is applying a rotational force at 90 degrees to the linkage which starts the door moving. There is also a curved track in the outer corner to help the mechanism glide easily around the corner. It is clearer if you watch full screen on youtube.
