10.6.8 does not mount afp file share, only mounts to parent folder

This article http://support.apple.com/kb/HT4538 states that 10.6.7 and later can mount files from a url such as afp://myserver.mydomain.com/Sharepoint/Folder/File.txt

However in 10.6.8 instead of opening the file, only the parent folder is mounted.

Was this issue not truely solved or are there some files that might need to be purged ?
