None of which changes the fact that the reference you provided was
simply WRONG, and unsafely wrong. An ISO 4038/DIN 74234 "bubble" flare
is nothing like a half completed SAE J5336 45 degree double lap flare.
Here is a somewhat authoritative document (it's from a brake line
importer) showing different flares -
http://www.fedhillusa.com/webnuts/common%20flares6.pdf

Who knows what angle is created by any particular SAE flaring tool on
the "half completed" part of the flare? DIN/ISO specs call for a 115
degree angle, with a 1 degree tolerance. There is no specification for
a "half completed" SAE flare, so even if one guy got it to work for his
purposes using the particular tool he had, there can be no guarantee
that any other tool would produce similar results, and certainly no
guarantee that any flare done that way would seal properly under full
working pressure. I certainly wouldn't drive a race car built by
someone who used that method.

(Oh, and if you want your grammar freedom to not properly quote and
attribute information, then you must take full credit/responsibility
for whatever you write)
