Tramp behaves as expected. You use an ad-hoc multi-hop remote file
name. Such ad-hoc definitions are removed when you call
`tramp-cleanup-all-connections'. This is described in the Tramp manual
(info "(tramp) Ad-hoc multi-hops")
(info "(tramp) Cleanup remote connections")

If you want to keep multi-hop definitions permanently, configure
`tramp-default-proxies-alist' as described in the Tramp manual, or set
`tramp-save-ad-hoc-proxies' to t. See (info "(tramp) Multi-hops")

Best regards, Michael.
