Ascend a Friend question...

Valua

Need some help clarifying something.

 

If I ascend a friend and they purchase a month of game time do I get a free month? Or is it only after their second month of paid time that I get the free month?

 

Wondering because if my friend can get me a free month after he purchases his first month we'll both go halves on his sub.

 

Thanks in advance for anyone who can help!
