[CentOS] questions on debuginfo.centos.org

Recently I add a debuginfo repo into my /etc/yum.repos.d/
<start>
[debuggery]
name=CentOS-$releasever - DebugInfo
baseurl=http://debuginfo.centos.org/$releasever/$basearch/
priority=1
<end>

then yum update and list shows

I notice that the kernel debuginfo version mismatch with my currenting
running kernel, then I go to the
site http://debuginfo.centos.org/5/i386/  , and there do exist the
following ones :

So, Is it the problem of debuginfo.centos.org/5/repodata or I missed anything?

Thanks and HAPPY NEW YEAR!
