Guys can you comment on this difference?

The spec file in question is:
http://pkgs.fedoraproject.org/cgit/syslinux.git/plain/syslinux.spec

Richard, you mentioned in this thread[1]:
"Mock is really just a python wrapper that allows you to build packages for
different versions of Fedora in a clean chroot with just the build
requirements specified in the spec file installed (and some standard ones)."

What "and some standard ones" stands for?

Rich, you mentioned in the same thread[2]:
"You don't really need to use mock either.  Just use 'rpmbuild -ba'
directly or 'fedpkg local' which is a wrapper."

Why this is not the case in this instance?

Clark, as maintainer of the Mock, and Lubomir, as maintainer of the shortrpm i.e. rpmbuild, 
you are also welcome to comment.
Adam and Kevin, too. :)
