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.

I do the second one quite far from the initial crimp for this reason. A few
quick tests have shown greater mechanical strength, if nothing else.

On the crimps I use this would be impossible, one wire in each and and
one squish at each end leaves very little of the connector unsquished.
