To first approximation, any time there is activity outside the minor set
there is an end effect. How confusing it is depends in large part on
often the dancers have encountered that effect.
There are dances where you work our way up and down the set turning or
passing by second, third, or even more neighbors before returning to
your original neighbor. At the ends you need to wrap around and treat
your partner as your nth neighbor. It's pretty straighforward if you
have enough dancers who have done it before, but the farther from home
you stray, the more confusing it gets to some people.
There is potential for disruption if the progression does not come at
the end of B2 and the couple at the end is showboating rather than
preparing to rejoin the line. That's always true, but more likely with
a double progression or any other nonstandard timing.

Hmm. OK, I seem to have answered my own specific question here, but
I'm still curious about the general issue of how to tell when a dance
is likely to have something tricky at the ends.
