From VmWare Knowledge Base:
The patch maintenance tool, esxupdate, was created to allow the installation of patches in random order. However, a flaw prevents the installation of older patches after newer patches (with an updated, overlapping RPM) is installed. In this situation, esxupdate returns the following messages, which indicate the bundle contains a package that has an older revision than what is already installed on the system:
INFO: 1 packages need to be downgraded.
Please use the --force option and try again.
