Several processes, every one owns a separate process buffer. But the
basic Tramp operations don't know which process is involved, therefore
the actual process is kept via the process connections "process-name"
and "process-buffer".

"Tramp" means the low level functions which communicate with
processes. Something like `tramp-send-command', `tramp-send-string' or
`tramp-maybe-open-connection'.
Best regards, Michael.
