I had to Google it. That is an interesting rule.Have you ever exprienced the Pittsburgh Left
We had something similar in NZ But it was when both vehicles were turning. The one crossing traffic had the right of way.
It actually used to be amazing as the one turning across traffic often couldn't turn as the straight oncoming cars made it impossible. But if you could see some indicate then you knew you could go in ahead of them. It got scrapped because too many tourists caused accidents. Pity, cause it was better.
The bottom one was dumb and needed fixing. It was only on unmarked intersections and if it was signposted, then the side street would be a Yield/Give Way
