From reading rule 18 it looks to me that port/starboard is completely irrelevant at this mark, and only the question of the inside overlap and when it was established matters.
I interpret it that way also, with A running so deep a line drawn across the back of A could stretch 250m back meaning A has to give mark room to all boats in the zone including B.
Thats all in the perfect world of the rule book of course.
The contradictory part of the rules is often A has boats to windward and a legal inside overlap established by B seconds before arriving at the mark doesn't allow A time or opportunity to give B room. One of the major changes I have noted in reading the 2009-2012 rules and interpretations is the concept of allowing the boat which has to give room, time and opportunity to give that room when the Right of Way boat first establishes it.
This thread is a very good idea, only a month ago, while sailing in a different class, someone was screaming mast a beam at me on the race course, that rule disappeared in the 80's
