The page actually offers a third option ... "Pacemaker 1.1 for CMAN or
Corosync 1.x". That's the configuration used by CentOS 6.

However, that's still a bit misleading; the documentation set for
"Pacemaker 1.1 for Corosync 2.x" is the only one that is updated, and
it's mostly independent of the underlying layer, so you should prefer
that set.

I plan to reorganize that page in the coming months, so I'll try to make
it clearer.
