In rsync man page:
A trailing slash on the source changes this behavior to avoid creating
an additional directory level at the destination.  You can think of a
trailing / on a source as meaning "copy the contents of this directory"
as opposed to "copy the directory by name", but in both cases the
attributes of the containing directory are transferred to the containing
directory on the destination.

Looks pretty documented to me.
