Ohh, that's annoying for me!
You are right, both are the same objects **until** I modify one of them. I mean:

  from.name = header.name
  => "AAAA"
  from.name. object_id == header.name.object_id
  => true

So in this moment from.name. object_id == header.name.object_id. But
if I change the value:

  from.name = "BBBB"
  from.name. object_id == header.name.object_id
  => false

Then from.name. object_id != header.name.object_id, so then there are
two values in memory at same time.

Regards.
