Yes, but why do we appear to think they would be using any vertical profile in 'the box' - might they not just be 'flying' it, and thus a million 'segments' would be irrelevant? The only JEPP plates I have, 2010, do not even have a whiff of any RNAV waypoints. Does the Dec 11 set have?
Discussion of RNAV 'criteria' is all well and good if relevant. What about an approach NOT using the 'box'? Do we know? What then? Good old 'airmanship', eh?
