usually not.
depending on your config, and how you actually use it, of course.

csync2 is push only.

it detects changes on the server you issue the command on,
and tries to push these changes to the other servers.

so short answer:

instead of
 ssh B "csync2 -xv",
you do
 ssh A "csync2 -xv",
again.

did I misunderstand the question?
