The choice is random as coded -- that's why the code generates a random number
and uses that in the sort. I guess you need a way to actually track where it
was in the sort order to begin with..
expand 2
gen random=uniform()
gen choicenum=_n
bysort id bl set (random): gen byte choice=_n==_N
Now you can see that the choice is set randomly to one of the two values of
choicenum in each set.

Thank you Michael,
What you proposed creates what I want apart from the fact that it does
not have the random assignment.
However, I think that I kind of need that. What I am trying to do is to
create individuals' choices from a choice experiment. Each individual
faces 3 questions (sets), which themselves consist of two alternatives.
If I was to always assign the "one" of the "choice" variable in the
second alternative that would mean that the individuals always choose
that alternative, which sound strange.
I know that it does not really matter, how I assign it since this is
just an exercise with simulated data but I was wondering if you could
think of a way to make the choice random.
Thanks a lot
