"cutting of a legal right-into-any-lane from the rightmost lane"

"its also possible for people to turn right from the middle lane of the source street into the rightmost lane of the target"

So you've created hypothetical situations that are no more useful than mine. I specifically mentioned having to turn into the nearest lane. If that's not true somewhere, then neither would adjacent turners be allowed. I simply asked if they were really cutting the other people off.
