I fail to see how it protects them from runners who nicked the card
earlier that day or bought it for a tenner from a fellow criminal who
did so.

Sure, but its presumably better than doing nothing at all.

I was seeking to contrast it with the protection offered by the
pre-authorization I mentioned earlier.

Sure, but it is less effort to do it their way and if they dont
get that many who deliberately show up with a maxed out
or stolen card, it may be a lot better than doing nothing.
