Hi Reza,
Thanks for spending time in helping answer Morteza's query so
well :)
As for your question, an intersection which is not a part of the road
( i.e. if it has been just dragged and dropped on to a road) will not
be connected to the road. The same if not noticed/rectified when
moderating also stands the risk of propagating to Maps.
In that sense, what you have explained above is indeed the right
course of action while dealing with such roads :)
