If the system preference 'ReservesControlBranch' is set to "Check the [item's
home library] to see if the patron can place a hold on the item.", the sub
CanBookBeReserved does not count holds on bilio level.

This is because there is no information about to which branch a biblio item
hold should refer.

The behaviour affects:

- putting holds from OPAC (if RequestOnOpac is set to  "[Allow] patrons to
place holds on items from the OPAC." (Seems always to be an biblio level hold)

- putting holds in staff interface for "Next available item" (= biblio level
hold)

Symptoms:

In OPAC, patrons can put more holds than allowed for an item type (up to
syspref 'maxreserve' = systemwide maximum holds)

Same in staff client as long you do not put item level holds. With other words:
You can put item level holds up to the maximum defined in the circulation rules
and additionally biblio level holds up to the value set in 'maxreserve'.

I think there is no way to overcome the situation (because a biblio has no home
library, only items can have), but it should be documented e.g. in the text
when setting the syspref 'ReservesContronBranch' and/or with a warning e.g. on
the page where the circulation rules are set.

I suppose that following Bugs could be related:

Bug 6976 - User hold limit can be avoided by users in OPAC
Bug 5159 - HomeOrHoldingBranch syspref description misleading 
Bug 4850 - CheckReserves does not respect holds circulation policies 
More?
