I kinda get tired of this 'fiddly Leica' film loading thing... Anyone can load an M3 quickly once they've given a go a few times. The other M's are quicker still. It's frankly a myth perpetuated by people who haven't used one.
The OP was referring to a LTM camera, not an M, at least the illustration would suggest it in the original article. And don't try to suggest that an original II/III is not fiddly - not only do you have to thread the film into the take-up spool, but you have to specially trim the leader to boot.
