You are confusing issues here somewhat.

The issue (and fix) described in that blog refers specifically to the 
proprietary NVIDIA drivers as installed by the NVIDIA installer where 
xorg-x11-server-Xorg and the NVIDIA installer will indeed conflict and 
each overwrite /usr/lib{64}/xorg/modules/extensions/libglx.so installed 
by the other. Thus, if you are using the NVIDIA installer then you will 
need to reinstall the NVIDIA drivers after each update to 
xorg-x11-server-Xorg to reinstate the NVIDIA libs just overwritten by 
the OS.

However, the RPM packaged driver solution installs conflicting libraries 
to separate locations (in this case 
/usr/lib{64}/xorg/modules/extensions/nvidia/libglx.so) and either the 
dynamic linker or an appropriately configured xorg.conf ensure the 
correct lib is loaded. So "upgrading the driver" with yum will never fix 
this issue as this is not broken in the first place with the packaged 
driver.
