That is a nonsense statement.  You can *never* overtake that which you 
are using as propulsion.  It is a logical impossiblity.  No matter
*what* 
you are using for propulsion.  The only issue here is whether gravity 
propagates at c or not.  The speed limit of this drive is the speed of
the 
gravity.
