If your "second" monster cup of hexagon monsters runs out when the herald is in play, do you still draw an additional monster from the main cup or not bother?

It's in the FAQ, pag. 35 (if you need the reference):

Q: What happens if you are supposed to draw a monster from each of the two cups during a new gate but there are none left in one cup?
A: Each monster that would be drawn from the empty cup is drawn from the other cup instead.
