Question about the 7 day system transfer wait time

I transferred an xl (A) to an original 3ds (B) a few days ago. I have a new xl (C) I want to transfer (B) to now. Obviously since the new xl (C) is new the 7 day thing has no relevance, but my question is does the original 3ds (B) have to wait 7 days to transfer to (C)? Or does the 7 day rule just mean you can't transfer a different 3ds and over-wright (B) again so soon?

Just wondering if it means you can't send/receive from a system for 7 days or just one or the other.
