Note the apparent disagreement between update and check-update about what will actually be done (and no nothing has changed on the repositories in the mean-time, I've rerun it and cleared the yum cache and the problem persists).

Is check-update using different logic than update?

Yes, it does. checkupdate only checks updates based on the repositoty

updates does depsolving, that handles the obsoleting you are seeing. In most cases you will see the same result but in this case the

perl-TermReadKey 2.30-3 -> 2.30-8 update detected by yum checkupdate

is overruled by the perl-Term-ReadKey obsoleting perl-TermReadKey when doing the 'yum update'
