You're right there.

WARNING, WARNING, WARNING :
ALL subfields connected to "items.*" koha table MUST be in the same tag.
It's somewhat logic : the biblio is unique, and you have many items that 
are located in differents branches. But you still have only one biblio.
1 MARC record = 1 biblio and ANY items of this biblio, located in any 
branch.

you're right. If it's not the case in default MARC21 parameters => a 
good idea would be to report a bug bugs.koha.org
