When importing a new record and matching the bib and 'replacing' the item, Koha
matches/overlays items on either barcode or itemnumber in the 952 $p or $9. 
However, it does not require that the item being overlaid be tied to the
bibliographic record being matched in the import process.

Example:
Bib record 1:
=LDR  01867cgm a2200433 a 4500
=020  \\$a1564589161
=245  00$aDog$h[videorecording] /$cBBC Wildvision ; BBC Lionheart Television
and Dorling Kindersley Vision in association with Oregon Public Broadcasting ; 
=999  \\$c39742$d39742
=952  \\$aMAIN$bMAIN$cJVI$oJVID 636.7 Jol$pTVSN5$yVHS$93600


Bib record 2:
=LDR  00925cam a22002775a 4500
=020  \\$a0716617471 (hbk.)
=100  1\$aMorley, Christine.
=245  00$aDog /$cChristine Morleyand Carole Orbell ; illustrations by Brita
Granström.
=999  \\$c35238$d35238
=952  \\$936713$aMAIN$bMAIN$cJVI$oJuv Mor$pBAR1$yVHS$95000


If you import the following record and use a 020$a matching rule you will match
on bib #1, but overlay the item on bib #2.  Koha gives no warning but simply
overlays.

=LDR  01867cgm a2200433 a 4500
=020  \\$a1564589161
=245  00$aDog$h[videorecording] /$cBBC Wildvision ; BBC Lionheart Television
and Dorling Kindersley Vision in association with Oregon Public Broadcasting ; 
=999  \\$c39742$d39742
=952  \\$aEAST$bEAST$oJVID 636.7 Jol$pBAR1$yVHS
or use the following item tag matching on the itemnumber
=952  \\$aEAST$bEAST$oJVID 636.7 Jol$p57890000012345$yVHS$95000


This could be a problem particularly with libraries using an acquisitions
process where items must be overlaid with new information.  Koha should check
to see that bib overlaid belongs to the bib that was matched before overlaying.
 Right now there is no indication that the overlay took place on a second
bibliographic record.
