That way it can deal with the inductive kick back of the wire as well as 
the coil.  Whether the wire contributes enough inductance to be significant 
is another question.  However, a component soldered to a PCB is less likely 
to be lost during maintenance than one attached to the terminals of a 
contactor coil.
