Good evening Allan, I'm not sure of the code reference for the IBC, but the 14 reference is 7.3.2(1) , 2010 ed.

I have never seen it and I have been checking for this for years and I would not be surprised if I have missed it. Related to this, the last time I looked IBC still says "connection for each floor" while 14 says "at the intermediate" landing which is one less connection per standpipe for many stairwell standpipes. In answer to the first question, sometimes it is possible to put the control valve at the landing below the floor level, rise up through the next landing and then exit the stairwell enclosure into the ceiling cavity. This would happen below the next floor's control valve. This method is possible when the conditions are right and when the architect is motivated enough to make enough room in the stairwell for all the trappings at a mid landing.
