They can go "inactive" and you can still get the points as long as when they come back they submit $1250. Any previous sales won't count... it starts fresh.
I just wanted to say that this is a HUGE change, but overall it is going to be a good thing. They are making it easier for all levels to promote. Just taking out the "qualifying" aspect of it is huge. To be an Advanced Director now, you only have to have one director under you.
