This one's particularly common in Edinburgh. In fact in the example they use - "Regent Road" connects to Princes Street, which becomes Shandwick Place, then Atholl Place. At this point the main fork becomes Dalry Road which then becomes Gorgie Road which becomes Stenhouse Road and then Calder Road - all of which are roughly a straight line:
I've relatives about six miles away from there in a residential close whose name is Ravenshaugh Crescent on the left, and Ravensheugh Crescent on the right.
Local council clearly made an error when putting the two named street signs on each side of the corner, nobody has ever known which one it was supposed to be in the first place, and so... this.
There's also the chance a single segment of the road has several names. For example when crossing a bridge or a round-about. Never mind all local names vs official names, old names and translations.
Correct, and indeed having the same name on different sides of the same road. I just recalled another example from Edinburgh[0] where one side of the street is called "Lochrin Buildings" while the other side of the street is called "Gilmore Place" (then both sides of the street become Gilmore Place, which then invisibly changes its name to Granville Place before changing into Polwarth Gardens.
