The intenmtion of file name quoting isn't to make a file name local or
remote. This is just a side-effect in case of Tramp.

The intention of file name quoting is to suppress file name handlers of
any kind.

"/:/method:user <at> host:/foo/bar.gz" makes "/method:user <at> host:/foo/bar.gz"
a literal file name, not to be transferred to any file name handler.

"/method:user <at> host:/:/foo/bar.gz" keeps the Tramp file name handler
active, but makes "/:/foo/bar.gz" a literal file name "/foo/bar.gz" on
the remote machine. This suppresses the jka-compr-handler, for example.

Likely, you mean the same, but I wanted to say it explicitly.

Best regards, Michael.
