Yes, the wider part goes round the outer end of the crimp, where the

once for each wire, keeping the wider part on the outside.

I always crimp 4 times, 2 for each wire. Paranoid, moi?

I doubt if this actually makes the crimp more secure, with the correct
tool for the crimp the tool is designed to squash the crimp just
enough and no more. If you then do it again I think you're likely to
damage (e.g. crack) the crimp and it certainly won't improve the
connection.
