The problem seems to be because of a change of name between 43 
and 4x.  

For example:
   yum-conf-43-... contains /etc/yum/repos.d/sl.repo
   yum-conf-4x-... contains /etc/yum.repos.d/sl4x.repo

Similarly sl-errata.repo -> sl4x-errata.repo

The repository files are flagged as "config" in the original RPMs so,
customised versions will not be replaced so long as the name relains the
same. Newer versions will be given the extension ".rpmnew".

This is not good packaging by SL.  It looks like you have to sl.repo and 
sl4x.repo customised versions.

I suspect that this problem will not occur again given the "4x" 
naming scheme, but I agree that the SL packaging did not make this clear.
