Oh, good point. Maybe it would be clearer to use two separate
flag variables?
The thought I'd had was that the flag would necessarily get reset
during the first iteration of the second loop, which means it all
ends up the same anyway. But if we want to think of the flag as
meaning two different things for the two loops, I'd be inclined to
use two variables.
