No, you can (and have always been able to) use an absolute restraint relative to 
the coordinate origin.  There are additional complications in this case (noted 
in the manual), so it's not often used.  The current setup that you're using is 
such that one group is moved with respect to the other.  So in effect, you are 
"moving only one group" but its position depends on the other.  In most cases, 
the absolute position of the reference group is irrelevant, though not always.
