Problems with the %{?_isa} macro in dependencies

Hi,

I have tried using the %{_isa} macro in a couple of my packages as 
instructed in 
<http://fedoraproject.org/wiki/Packaging:Guidelines#Explicit_Requires> 
and I'm having problems with it.


First case:
The arch-specific libvoikko spell checking package requires the Finnish 
morphology, which is in the arch-specific malaga-suomi-voikko package. I 
did the following change (the versioned dependency was unnecessary):
-Requires:       malaga-suomi-voikko >= 1.4
+Requires:       malaga-suomi-voikko%{?_isa}

Now AutoQA's depcheck says there is a problem with the i686 dependency 
on x86_64: 
<http://autoqa.fedoraproject.org/results/198794-autotest/10.5.124.164/depcheck/results/libvoikko-3.3.1-0.2..html>

"SKIPBROKEN: libvoikko-3.3.1-0.2.rc1.fc16.i686 from pending has 
depsolving problems
SKIPBROKEN:  --> Package: libvoikko-3.3.1-0.2.rc1.fc16.i686 (pending)
   -->     Requires: malaga-suomi-voikko(x86-32)"


Second case:
I'm renaming the openoffice.org-voikko package to libreoffice-voikko.
Review request: <https://bugzilla.redhat.com/show_bug.cgi?id=739331>,
spec: <http://vpv.fedorapeople.org/packages/libreoffice-voikko.spec>.

The Provides and Obsoletes are as follows:
Provides:         openoffice.org-voikko = %{version}-%{release}
Obsoletes:        openoffice.org-voikko < 3.1.2-6

This works, but if I change the Obsoletes to
Obsoletes:        openoffice.org-voikko%{?_isa} < 3.1.2-6
then the package does not obsolete openoffice.org-voikko any more, which 
results in file conflicts.

Could someone please explain what's going on here?
