Previews being spoilers is pretty standard fare in most genre programs.

I remember quite famously the BBC getting destroyed by spoiling the "death/not death" of a character on Doctor Who a few years back by showing the preview BEFORE the credits.

Since only what is broadcast on the show is canon, it's doesn't seem like such a leap that the events you describe are not.
