If so why? I know setting this on will result in more number of automatically committed revisions. Is it good to have more auto commits?

            You can turn this on to offer WebDav mappings, most OSes can make network mappings to http(s):// URLs.
If SVNAutoversioning is off, files cannot be saved to these mappings.
