That's not involving QgsAttributeTableModel, so this seems to be a
different issue.

In your case, it's dangerous to use the feature ids from one layer and
assume that they match on another layer. You will have to find a common
attribute (primary key) or (I guess you create one of the two layers in
your script) copy the source feature id to the copied layer.
