soap:header using same message as SOAP Body

Can someone explain what happens when a soap:header references a part
within the same message as the one defining the SOAP Body?
Do we end up with just one part in the Header or
there are two independent instances of the part,
one in the Header and one in the Body?
Will the parameter of the call corresponding to the part
end up in the Header or the Body?

Thanks
