Here's an illustrated example from a Python Shell:
>>> p1 = hou.parm('/obj/torus_object1/tx')
>>> p2 = hou.parm('/obj/torus_object1/ty')
>>> try: p2.expression()
... except: print "no expr"
>>> print "has ref:", p1.getReferencedParm() != p1
has ref: True
>>> print "has ref:", p2.getReferencedParm() != p2
has ref: False
