I'm not an expert in the internals, but it looks to me that the IR lists the 
properties with below the property, a default.  Thus the default font-shape 
is 'italic, and the default direction is given by 
tuplet-number::calc-direction.  Direction has an argument of (direction) and 
it therefore expects a direction as the argument.  In this case, #UP is a 
possible argument.
