It's not quite that.  In the definition above, a treble clef on the 5th staff 
of a system is cross-staff because its placement depends on what is contained 
in the systems above.  What will not change is its placement with respect to 
its staff.  I like "Any grob that is not the element of a vertical axis group 
or whose relative extent with respect to the vertical axis group of which it is 
an element changes as a result of how far apart two or more vertical axis 
groups are." This opens up the definition to all vertical axis groups (i.e. 
Dynamics, ChordNames). But it is obviously too technical for a docstring.
