In B1 the gents hold on after the allemande right, put their arm around their partner (gent's arm below), and turn halfway more. This star promenade uses different arms than "usual", with the nice consequence that partners are rotating the right direction for a smooth transition into the swing. And since the gent's left and lady's right arms are already connected it's a great chance to use the "hoop hold" (seen sometimes in Scandinavian turning dances) where both partners make a big hoop with their arms, supporting each other equally. It might profit from a quick demo since many dancers don't use it.

In B2 the "wrong side" reverse progression can come as a surprise, but the last two figures give a quick satisfying resolution to get everyone back on the "right" side.
