Yes, that's right. More precisely, no upgrades or installs for openoffice packages. Consult man yum.conf to be sure.
The echo command adds this line at the end of /etc/yum.conf file

'echo exclude=openoffice* >> /etc/yum.conf' explained:
echo simply echoes the string, however, the '>>' redirection sends the output to file '/etc/yum.conf' in append mode. Using '>' would overwrite the file, '>>' does append to the end. The command is an equivalent for opening the /etc/yum.conf in a text editor and then adding 'exclude=openoffice*' to the end of the file.
