In answer to the questions about why the promotion only applies to certain seats, I believe that the $10 tickets are only for the last 100 seats in the mezzanine. The Studio 54 mezzanine is much larger than the American Airlines mezzanine is, so the $10 seats are much farther back at Studio 54.
It does raise the interesting question, though, of why After Miss Julie is at the American Airlines Theater and Wishful Drinking is at Studio 54. Wishful Drinking is a one-woman show that would probably be better suited to the smaller American Airlines Theater, and I agree that ticket demand would probably be higher for After Miss Julie as well, so it seems that the shows should switch places.
(After Miss Julie is a relatively small show as well (there are only 3 cast members), and it was announced first, so maybe it just got first dibs on the theater it was best suited for, and Wishful Drinking just had to make do.)
