The attached screenshot shows the result after the undo. I'll describe how it got there in prose. Initial condition was green wire connections: far left chest -> electric pole -> station. I deleted the electric pole and the green wire from the station automatically connected to the far left chest. I then undid the pole deletion and the station now connects to the far left chest and the electric pole. The state of the wire connections did not return to the start.
In summary:
green wire: chest -> pole -> station
delete pole
green wire: chest -> station
undo
green wire: chest -> pole -> station and chest -> station
