Well, the answer to this question in relation to CentOS is easy.  When
Red Hat releases a package for RHEL (any package, java-1.7.0-openjdk or
anything else), then we build it.

As to what Red Hat selects, when they select it or why, or any of the
other questions you have ... we have no idea.  We build what they
release when they release it on our build system.

Someone who has RHEL-6.5 might be able to post the java -version from
that package as a comparison.
