These ('scissor stairs') are an important part of the discussion here. They are allowed (or counted as two separate means of exit) in New York, Australia, Vancouver, etc. but not permitted (or counted as one means of exit) in most of the rest of the USA, the UK, etc.
For a high rise building they don't take up much more space than a single stair and can play an important role in the structure of the building also.
