If you don't specify --delete-during (--del) or --delete-after, the

The --delete option may be combined with one of the --delete-WHEN options
without conflict, as well as --delete-excluded. However, if none of the
--delete-WHEN options are specified, rsync will currently choose the
--delete-before algorithm. A future version may change this to choose the
--delete-during algorithm. See also --delete-after.

or --delete-excluded is specified without one of the --delete-WHEN options.
See --delete (which is implied) for more details on file-deletion.
Deleting before the transfer is helpful if the filesystem is tight for space
and removing extraneous files would help to make the transfer possible.
However, it does introduce a delay before the start of the transfer,
and this delay might cause the transfer to timeout (if --timeout was
specified).
