I think it's related to instroke being device dependant, as I say in
the other message.

Well, I figured with 0 setlinecap the last point would be on the edge,
and there would be a 50/50 possibility of it being painted. I can catch
it with 2 setlinecap.

The path has only a first part which is invisible, and maybe a black
second part. If it has a black second part, it doesn't matter which
part of it touches the last point, we are just interested in that it
is there (so we can add the length of the invisible first part). So, it
isn't necessary to reduce the line width. In fact, enlarging it could
be more helpful.
