The action depends on 4 couples for the progression. As the action
alternates the two couples on each end swap every other cycle via the cast
off, but those dyads stay segregated - there is no "move up" or similar to
mix further numbers of couples from the middle of the line into the A parts
active position. As written, 4 (alternating) times through the dance will
make every couple "active" once.
I view this dance as a handy alternative to running a square for those
times when you'd be stuck for something else.

Need it be limited to 4 couples? Would an arbitrarily
long line work?
