hello...
The link you provided provides editing rules when “a single-lane roadway intersects a two-lane roadway,” and this rule has nothing to do with this node, which we are talking about...
Moreover, you set the turn restrictions incorrectly - instead of “straight only” you used the “straight and left” restriction (i.e. right turns are prohibited)..
Taking into account all that has been said, I removed the node point and I think this is the right decision...
Sincerely...
