It's a different branch. The 4.x branch had/has continued support even though the 5.x (and now 6.x) branches are released.
Every branch of Enterprise Linux is supported with updated for 7 years ... that is the purpose of Enterprise Linux. This is as compared to the standard Linux distributions that usually have 1 year (current and last version ... release every 6 months).
More info here for the upstream ... CentOS mirrors all but the "Extended Life Cycle":

(CentOS would also mirror the Extended Life Cycle, but we can not get the SRPMS from the upstream provider)
