Correct.  It exists (as a last resort) to get the nominated value into the
xy file.  Because the angle determination isn't very smart, and probably 
can't ever be made smart enough.  Yes, in particular non-90'd rotations are 
not handled automatically at all.  

There's also another undoc'ed attribute "xy-centre" which if you set to "origin" 
changes the location written into the xy file to be the element's actual origin
rather than the element's "pad/pin centre of mass".  Which is needed for
BGAs/PGAs with missing corner pins.
